5 Channel coding, multiplexing and interleaving

Data and control streams from/to MAC layer are encoded /decoded to offer transport and control services over the radio transmission link. Channel coding scheme is a combination of error detection, error correcting, rate matching, interleaving and transport channel or control information mapping onto/splitting from physical channels.

5.1

Generic procedures

This section contains coding procedures which are used for more than one transport channel or control information type.

5.1.1

CRC calculation

Denote the input bits to the CRC computation by 13210,...,,,,-A a a a a a , and the parity bits by 13210,...,,,,-L p p p p p . A is the size of the input sequence and L is the number of parity bits. The parity bits are generated by one of the following cyclic generator polynomials:

- g CRC24A (D ) = [D 24 + D 23 + D 18 + D 17 + D 14 + D 11 + D 10 + D 7 + D 6 + D 5 + D 4 + D 3 + D + 1] and; - g CRC24B (D ) = [D 24 + D 23 + D 6 + D 5 + D + 1] for a CRC length L = 24 and; - g CRC16(D ) = [D 16 + D 12 + D 5 + 1] for a CRC length L = 16. - g CRC8(D ) = [D 8 + D 7 + D 4 + D 3 + D + 1] for a CRC length of L = 8.

The encoding is performed in a systematic form, which means that in GF(2), the polynomial:

23122221230241221230......p D p D p D p D a D a D a A A A ++++++++-++

yields a remainder equal to 0 when divided by the corresponding length-24 CRC generator polynomial, g CRC24A (D ) or g CRC24B (D ), the polynomial:

15114141150161141150......p D p D p D p D a D a D a A A A ++++++++-++

yields a remainder equal to 0 when divided by g CRC16(D ), and the polynomial:

7166170816170......p D p D p D p D a D a D a A A A ++++++++-++

yields a remainder equal to 0 when divided by g CRC8(D ).

The bits after CRC attachment are denoted by 13210,...,,,,-B b b b b b , where B = A + L . The relation between a k and b k is:

k k a b =

for k = 0, 1, 2, …, A -1 A k k p b -=

for k = A , A +1, A +2,..., A +L -1.

5.1.2 Code block segmentation and code block CRC attachment

The input bit sequence to the code block segmentation is denoted by 13210,...,,,,-B b b b b b , where B > 0. If B is larger than the maximum code block size Z , segmentation of the input bit sequence is performed and an additional CRC sequence of L = 24 bits is attached to each code block. The maximum code block size is: - Z = 6144.

If the number of filler bits F calculated below is not 0, filler bits are added to the beginning of the first block.

Note that if B < 40, filler bits are added to the beginning of the code block. The filler bits shall be set to at the input to the encoder. Total number of code blocks C is determined by: if Z B ≤ L = 0

Number of code blocks: 1=C

B B ='

else L = 24

Number of code blocks: ()??L Z B C -=/.

L C B B ?+='

end if

The bits output from code block segmentation, for C ≠ 0, are denoted by ()13210,...,,,,-r K r r r r r c c c c c , where r is the code block number, and K r is the number of bits for the code block number r .

Number of bits in each code block (applicable for C ≠ 0 only):

First segmentation size: +K = minimum K in table 5.1.3-3 such that B K C '≥?

if 1=C

the number of code blocks with length +K is +C =1, 0=-K , 0=-C

else if 1>C Second segmentation size: -K = maximum K in table 5.1.3-3 such that +

-+-=?K K K

Number of segments of size -K : ???

????'-?=+-K B K C C .

Number of segments of size +K : -+-=C C C . end if

Number of filler bits: B K C K C F '-?+?=--++ for k = 0 to F -1

-- Insertion of filler bits

end for k = F s = 0

for r = 0 to C -1 if -

-=K K r

else

+=K K r

end if

while L K k r -< s rk b c = 1+=k k

1+=s s

end while if C >1

The sequence ()13210,...,,,,--L K r r r r r r c c c c c is used to calculate the CRC parity bits ()1210,...,,,-L r r r r p p p p

according to section 5.1.1 with the generator polynomial g CRC24B (D ). For CRC calculation it is assumed that filler bits, if present, have the value 0. while r K k <

)(r K L k r rk p c -+=

1+=k k end while

end if 0=k

end for

5.1.3 Channel coding

The bit sequence input for a given code block to channel coding is denoted by 13210,...,,,,-K c c c c c , where K is the

number of bits to encode. After encoding the bits are denoted by )(1)(3)(2)(1)(0,...,,,,i D i i i i d d d d d -, where D is the number of encoded bits per output stream and i indexes the encoder output stream. The relation between k c and )(i k d and between

K and D is dependent on the channel coding scheme.

The following channel coding schemes can be applied to TrCHs: - tail biting convolutional coding; - turbo coding.

Usage of coding scheme and coding rate for the different types of TrCH is shown in table 5.1.3-1. Usage of coding scheme and coding rate for the different control information types is shown in table 5.1.3-2. The values of D in connection with each coding scheme: - tail biting convolutional coding with rate 1/3: D = K ; - turbo coding with rate 1/3: D = K + 4.

The range for the output stream index i is 0, 1 and 2 for both coding schemes.

Table 5.1.3-1: Usage of channel coding scheme and coding rate for TrCHs.

Table 5.1.3-2: Usage of channel coding scheme and coding rate for control information.

5.1.3.1 Tail biting convolutional coding

A tail biting convolutional code with constraint length 7 and coding rate 1/3 is defined. The configuration of the convolutional encoder is presented in figure 5.1.3-1.

The initial value of the shift register of the encoder shall be set to the values corresponding to the last 6 information bits in the input stream so that the initial and final states of the shift register are the same. Therefore, denoting the shift register of the encoder by 5210,...,,,s s s s , then the initial value of the shift register shall be set to

()i K i c s --=1

0 = 133 (octal)

1 = 171 (octal)

2 = 165 (octal)

Figure 5.1.3-1: Rate 1/3 tail biting convolutional encoder.

The encoder output streams )

0(k d , )1(k d and )2(k d correspond to the first, second and third parity streams, respectively as

shown in Figure 5.1.3-1.

5.1.3.2

Turbo coding

5.1.3.2.1

Turbo encoder

The scheme of turbo encoder is a Parallel Concatenated Convolutional Code (PCCC) with two 8-state constituent encoders and one turbo code internal interleaver. The coding rate of turbo encoder is 1/3. The structure of turbo encoder is illustrated in figure 5.1.3-2.

The transfer function of the 8-state constituent code for the PCCC is: G (D ) = ??

???)()(,

101D g D g ,

where

g 0(D ) = 1 + D 2 + D 3,

g 1(D ) = 1 + D + D 3.

The initial value of the shift registers of the 8-state constituent encoders shall be all zeros when starting to encode the input bits.

The output from the turbo encoder is

k k x d =)0( k k z d =)1( k k z d '=)2(

for 1,...,2,1,0-=K k .

If the code block to be encoded is the 0-th code block and the number of filler bits is greater than zero, i.e., F > 0, then

the encoder shall set c k , = 0, k = 0,…,(F -1) at its input and shall set >==

The bits input to the turbo encoder are denoted by 13210,...,,,,-K c c c c c , and the bits output from the first and second 8-state constituent encoders are denoted by 13210,...,,,,-K z z z z z and 13210,...,,,,-'''''K z z z z z , respectively. The bits output

from the turbo code internal interleaver are denoted by 110,...,,-'''K c c c , and these bits are to be the input to the second 8-state constituent encoder.

Figure 5.1.3-2: Structure of rate 1/3 turbo encoder (dotted lines apply for trellis termination only).

5.1.3.2.2 Trellis termination for turbo encoder

Trellis termination is performed by taking the tail bits from the shift register feedback after all information bits are

encoded. Tail bits are padded after the encoding of information bits.

The first three tail bits shall be used to terminate the first constituent encoder (upper switch of figure 5.1.3-2 in lower position) while the second constituent encoder is disabled. The last three tail bits shall be used to terminate the second constituent encoder (lower switch of figure 5.1.3-2 in lower position) while the first constituent encoder is disabled. The transmitted bits for trellis termination shall then be:

K K x d =)0(, 1)0(1++=K K z d , K K x d '=+)0(2, 1)

0(3++'=K K z d K K z d =)1(, 2)1(1++=K K x d , K K z d '=+)1(2, 2)1(3++'=K K x d 1)2(+=K K x d , 2)2(1++=K K z d , 1)

2(2++'=K K x d , 2)2(3++'=K K z d

5.1.3.2.3 Turbo code internal interleaver

The bits input to the turbo code internal interleaver are denoted by 110,...,,-K c c c , where K is the number of input bits.

The bits output from the turbo code internal interleaver are denoted by 110,...,,-'''K c c c . The relationship between the input and output bits is as follows:

()i i c c ∏=', i =0, 1,…, (K -1)

where the relationship between the output index i and the input index )(i ∏ satisfies the following quadratic form:

()

K i f i f i m od )(221?+?=∏

The parameters 1f and 2f depend on the block size K and are summarized in Table 5.1.3-3.

5.1.4

Rate matching

5.1.4.1

Rate matching for turbo coded transport channels

The rate matching for turbo coded transport channels is defined per coded block and consists of interleaving the three

information bit streams )0(k d , )1(k d and )2(k d , followed by the collection of bits and the generation of a circular buffer as

depicted in Figure 5.1.4-1. The output bits for each code block are transmitted as described in section 5.1.4.1.2.

多功能切菜机设计(有CAD图)

第1章绪论 1.1课题背景 20世纪以来，我国食品工业较改革开放初期有了很大的发展，人民生活有了很大的改善，日益对食品加工和食品包装提出了更高的要求。发展食品工业的基础便是食品机械。不断地研制各种类型的食品机械来促进食品工业的发展，以满足不断提高的人民物质和文化生活的需要，使人们从繁重的家务劳动中解放出来，而以更充裕的时间投入到工作中去。因此研制先进的食品机械，使食品加工迅速地实现机械化和自动化是社会发展必然趋势。随着经济的发展,人们物质生活水平的不断提高,人们的饮食习惯逐步向方便,快捷,营养化发展，在蔬菜的加工方面出现了净菜半成品菜，受到广大人民群众的欢迎。随之而来，半成品菜的加工成为难题。虽然中国劳动力低廉，但手工切出的制品不卫生，规格尺寸不均，破损量大，成本相对较高。食品加工机械的动力部分是电动机。它们可以代替人们的手工劳动或作为其补充。它们均服务于各种菜肴食料的准备与制作，或者服务于与此相同的其他辅助性工作。食品加工机械有一个动力部分，一个与其固定在一起或者根据操作的需要可以拆卸的工作部分与若有此必要的附配件所组成。食品加工机械的种类有很多,可分为:搅拌及揉合设备,搅合机具,切削器具,切片器具,榨汁机,咖啡机,搅肉机,制糜机,开罐头机等等。多功能、高生产率的食品切菜机，它代表了食品机械发展进入一个新的历史时期。因为它可以广泛地应用到食品加工厂、菜市场、果品厂、酱菜厂、厂矿、机关、学校、旅店食堂等等。目前，国内生产切菜机的厂家不多，现在我国的食品机械行业的主要机器型号有JY-Q550型多功能切菜机,PQT-580型多功能切菜机（整机（无级）：1200×700×300MM,外形尺寸：送料槽：长×宽=1000×140MM）；CHD40型推杆式切菜机QD-DLC2智能型蔬菜切割机；QCJ-Ⅰ型多功能切菜机TW-801A多功能切菜机,机器尺寸：1160（L）×530（W）×1000（H）(mm)机器重量：135KG切割尺寸1-60mm(叶菜部)产量：300-100kg/HR电源：220V单相马力：3/4HP皮带宽：120mm；DQ180A、

频率来满足不同的切削要求。此类切菜机体积庞大、效率高、能耗大，主要用来满足大型食品加工厂或者大型的食堂等蔬菜需求量大的场所使用。依据功能主要分为两类：单切型和多功能型切菜机。单切型切菜机适用于片、段、丝、块茎、叶菜类的蔬菜的切削，一般多用于食品加工厂，专机专用，例如土豆切丝机等，可以提高产品的生产效率。典型结构为箱式。多功能型切菜机在单切型的基础上，将片、丝等切削功能融于一身，同时可对不同类别的蔬菜圆进行加工，丰富了产品的加工对象。此类切菜机多用于大型饭店等场所。多功能型切菜机按结构可分为两类：双头型切菜机：一头专切叶菜类，由传送带送菜，往复运动的刀具进行切削；另一头专切土豆等根茎类、块类蔬菜，原料从倾斜的料筒送入，由旋转刀具进行切削，可同时工作，通过更换刀盘，可以切出各种规格的片、丝、条。组合式切菜机：水平传送带传送原料，由在传送带上间隔分布的成一定角度的多个刀具进行切削，根据需要原料在传送带上经一次或多次切削后成形，成品的形状参数通过调节刀具的切削速度及原料的传送速度来控制。 1.2 切菜机的发展趋势通过对市场上的切菜机观察了解，对其结构和功能对比分析发现，切菜机的发展主要倾向于以下这两个特点：（1）功能集成化在保证基本功能的同时，同过对结构修改和优化，将不同产品的功能融于一身，实现一机多用，提升产品的使用价值，降低产品的成本。类似于豆浆机和榨汁机的融合，既减轻了消费者的成本，又提升了产品的市场竞争力。（2）规格两极化切菜机是一种蔬菜加工机械，其适用范围因地点而异。大规模的食品加工厂和酒店，需要高效率、全自动化的切菜机设备，同时对其加工效果的要求也会不断提高。但是随着生活水平的提高，人们对家庭生活的舒适度要求也在提
