Description

一种准循环低密度奇偶校验编码处理方法及装置 技术领域
本发明实施例涉及通信技术领域,尤其涉及的是一种准循环低密度奇偶校验(Low Density Parity Check,简称LDPC)编码处理方法及装置。
背景技术
图1是根据相关技术的数字通信系统的结构框图,如图1所示,数字通信系统中,一般包括三个部分:发送端、信道和接收端。发送端可对信息比特序列进行信道编码从而获取编码码字,对编码码字进行交织,并将交织后的比特映射成调制符号,然后可以根据通信信道信息来处理和发送调制符号。在信道中,由于多径、移动等因素导致特定的信道响应,这些都会使数据传输失真,同时由于噪声和干扰也会进一步恶化数据传输。接收端接收通过信道后的调制符号数据,此时的调制符号数据已经失真,需要进行特定处理才能恢复原始信息序列。
根据发送端对信息序列的编码方法,接收端可以对接收数据进行相应处理从而可靠地恢复原始信息比特序列。所述的编码方法必须是收发两端都是可见的。一般地,所述编码处理方法是基于前向纠错(Forward Error Correction,简称FEC)编码,其中,前向纠错编码在信息序列中添加一些冗余信息。接收端可以利用该冗余信息来可靠地恢复原始信息序列。
在发送端,需要对待传输的传输块进行码块分割获得多份小传输块,然后对多份小传输块分别进行FEC编码,所述待传输的传输块具有一定传输块长度(Transport Block Size,简称TBS)和编码码率,FEC编码码率一般定义为进入编码器的原始信息比特序列的比特数目与实际传输比特序列(或速率匹配输出序列)的比特数目的比值。在长期演进(Long Term Evolution,简称LTE)通信系统中,传输块大小比较灵活,从而可以满足LTE通信系统的各种传输数据包大小需求;以及LTE通信系统采用调制编码方案(Modulation and Coding Scheme,简称MCS)索引来指示调制阶数和编码 码率R的不同组合;通过一些控制信息,如下行控制信息(Downlink Control Information,DCI)或者信道质量指示(Channel Quality Indication,CQI)等确定TBS索引,以及根据资源块(Resource Block,RB)数目和TBS索引来共同确定实际信息比特序列的大小。信道类型中可以包括数据信道和控制信道,数据信道一般承载的是用户设备(User Equipment,简称UE)的数据,控制信道承载控制信息,包括MCS索引号、信道信息、DCI、CQI等控制信息。带宽大小一般是指系统分配给数据传输所占用的频谱宽度,LTE系统中分为20M、10M、5M等带宽。数据传输方向包括上行数据和下行数据,所述上行数据一般是指用户设备向基站传输数据,下行数据是指基站向用户设备传输数据。
一些常见的FEC编码包括:卷积码、Turbo码和低密度奇偶校验(Low Density Parity Check,简称LDPC)码。FEC编码过程中,对比特数目为k的信息序列进行FEC编码获得n比特的FEC编码码字(冗余比特为n-k)。LDPC码是一种可以用非常稀疏的奇偶校验矩阵或者二分图定义的线性分组码,正是利用它的校验矩阵的稀疏性,才能实现低复杂度的编码和译码,从而使得LDPC走向实用化。经过各种实践和理论证明,LDPC码是在加性高斯白噪声(Additive White Gaussian Noise,简称AWGN)信道下性能最为优良的信道编码,性能非常靠近香农极限。
在IEEE802.11ac、IEEE802.11ad、IEEE802.11aj、IEEE802.16e、IEEE802.11n、微波通信以及光纤通信等中,LDPC码都获得大量应用。LDPC码的奇偶校验矩阵中,每一行都是一个奇偶校验码,每一行中如果某一索引位置元素值等于1则说明该比特参与到该奇偶校验码,如果等于0,则说明该位置比特不参与该奇偶校验码。由于准循环LDPC编码(quasi-cyclic LDPC)描述非常简单,以及译码器结构简单,所以其在多种通信标准中获得应用。准循环LDPC编码也可以称为结构化LDPC编码,其奇偶校验矩阵H为mb×Z行和nb×Z列的矩阵,它是由mb×nb个子矩阵构成,每个子矩阵都是大小为Z×Z的基本置换矩阵的不同幂次,所述基本置换矩阵是单位的右循环移位(或左循环移位1)1位获得矩阵;也可以认为每个子矩阵是大小为Z×Z单位阵的右循环移位(或左循环移位)若干位所获得的子矩阵。此时,只要知 道循环移位值以及子矩阵大小就可以确定一个准循环LDPC码,对应每个子矩阵的所有移位值构成一个mb×nb矩阵,所述mb×nb矩阵可以称为基础矩阵或者基础校验矩阵或者原模图(base protograph,或base graph),所述子矩阵大小可以称为扩展因子或者提升值(lift size)或者子矩阵大小,在此描述为提升值。由于所述准循环LDPC码的构造非常紧凑和结构简单,而且非常有利于译码器实现,所以所述准循环LDPC码也称为结构化LDPC码。依照准循环LDPC码定义,准循环LDPC码的奇偶校验矩阵有如下的形式:
Figure PCTCN2017085786-appb-000001
如果hbij==-1,则
Figure PCTCN2017085786-appb-000002
是大小为Z×Z的全零方阵,如果hbij≠-1,则
Figure PCTCN2017085786-appb-000003
等于基本置换矩阵P的hbij次幂;为了从数学上更容易描述单位阵的循环移位,以上所述的准循环LDPC码基础矩阵中,在这里定义一个大小Z×Z的基本置换矩阵P,对单位阵的循环移位即对基本置换矩阵P进行相应大小的幂次,所述的基本置换矩阵P如下所示:
Figure PCTCN2017085786-appb-000004
通过这样的幂次hbij就可以唯一标识每一个分块矩阵,如果某一分块矩阵为全零方阵,基础矩阵中一般用-1来表示或者空值表示;而如果是单位阵的循环移位s获得,则等于s,所以所有hbij可以构成一个基础矩阵Hb,进而LDPC码的基础矩阵(或者基础校验矩阵)Hb可以表示如下:
Figure PCTCN2017085786-appb-000005
所以,准循环LDPC码完全可以由基础矩阵Hb和提升值Z唯一确定,因 而准循环LDPC码的基础矩阵Hb中包括2种元素:指示全零方阵的元素和用于指示单位阵循环移位的移位大小的元素,所述用于指示全零方阵的元素是一般用-1来表示或者空值表示,所述用于指示单位阵循环移位的移位大小的元素采用0至(Z-1)的一个整数表示。基础矩阵Hb中,任意行中如果存在q个非-1元素(用于指示单位阵循环移位的移位大小的元素),则认为所述行的行重为q,同理,也可以定义列重为基础矩阵Hb中任意列中的所有非-1元素(用于指示单位阵循环移位的移位大小的元素)的数目。基础矩阵包括多个参数:mb、nb和kb,其中,mb是基础矩阵行数(等于基础矩阵的校验列数),nb基础矩阵总列数,而kb=nb-mb是基础矩阵的系统列数。
例如,基础矩阵Hb(2行4列)如下而且提升值z等于4:
Figure PCTCN2017085786-appb-000006
则奇偶校验矩阵为:
Figure PCTCN2017085786-appb-000007
由于准循环LDPC码字是系统码,即码字中的系统比特与编码前的信息比特相等,所以在准循环LDPC编码中只要计算出校验比特即可。依据以上的奇偶校验矩阵即可进行准循环LDPC编码。例如奇偶校验矩阵H可以描述为2部分:H=[Hs;Hp],其中Hs对应系统比特矩阵,Hp对应校验比特矩阵,根据LDPC编码原理,对于准循环LDPC码字C(包括系统比特Cs,校验比特Cp),满足条件H×C=0,即[Hs;Hp]×[Cs;Cp]=0;从而可以推导出Hs×Cs=Hp×Cp,于是Cp=(Hp)-1×Hs×Cs,其中,公式中的‘×’是二进制矩阵乘法计算,(x)-1是二进制矩阵求逆计算;于是就可以计算出准循环LDPC码字的校验比特Cp,从而获得准循环LDPC码字C=[Cs;Cp]。
以上所述的准循环LDPC码中,基础矩阵中每个元素位置只有1个移位值 或者-1值,可以将其称为准循环LDPC编码的边数等于1,即基础矩阵中对应非-1元素位置只有1个移位值;而对于准循环LDPC编码中还有对应边数大于1的基础矩阵,即基础矩阵中的非-1元素位置包含多个移位值,即对应于奇偶校验矩阵来说,子矩阵由多个单位阵的循环移位叠加在一起构成,此时可以称为准循环LDPC编码的边数大于1,例如,基础矩阵Hb(2行4列)如下而且提升值z等于4,由于基础矩阵中非-1元素位置最多包含2个移位值,所以所述示例基础矩阵的边数等于2,基础矩阵的边数等于基础矩阵中非-1元素位置中移位值的最大数目:
Figure PCTCN2017085786-appb-000008
则奇偶校验矩阵为:
Figure PCTCN2017085786-appb-000009
在进行LDPC编码过程中,对待传输的原始信息数据(即信息比特序列)经过编码处理,其中处理过程可以包括:首先,需要对信息比特序列进行填充(padding)哑元比特(所述哑元比特收发端已知,不需要传输),使得填充后的比特序列长度达到LDPC编码的系统比特长度,如果信息比特序列的长度等于系统比特长度则无需填充;其次,对填充后的信息比特序列进行准循环LDPC编码,获得LDPC编码输出序列;然后,对所述LDPC编码输出序列进行比特选择,获得速率匹配输出序列,所述信息比特序列的长度与所述速率匹配输出序列的长度的比值就是所述速率匹配输出序列的码率;最后,发送所述速率匹配输出序列。对于接收端来说,则需要执行的译码过程如下:首先,接收完发送端发送的数据,一般是对数似然比(Log Likelihood Ratio,LLR)序列(或者,可以描述为软序列或者软比特信息序列);其次,对接收 到的对数似然比序列进行解比特选择(或者解速率匹配),并将对应发送端所填充的哑元比特位置的数据赋值为较大数值(如无穷大),从而获得和发送端的LDPC编码输出序列一样长的待译码对数似然比序列;然后,对所述待译码对数似然比序列进行LDPC译码,获得LDPC译码输出序列;最后,从LDPC译码输出序列中去除填充的哑元比特,即可获得所要接收的原始数据(或者发送端发送的信息比特序列)。
在LDPC编码和译码中,为了保证得到性能优异、吞吐量高、灵活性高和复杂度低等特性,与设计的LDPC码奇偶校验矩阵是息息相关的。反之,如果设计LDPC奇偶校验矩阵不好,将使得其性能下降,同时也可能会使得复杂度和灵活性受到影响。
虽然准循环LDPC码已经在多种通信标准中获得应用,但是经过分析可以发现,各种标准的码率和码长都是比较有限的,即灵活性比较差,以及比较难兼容各种应用场景,以及译码设计在不同条件下的译码算法不同带来的复杂度不一定较优。例如,在IEEE802.11ad标准中,只有1种码长(672)和4种码率(1/2、5/8、3/4、13/16);在IEEE802.11n标准中,只有3种码长(648、1296、1944)和4种码率(1/2、2/3、3/4、5/6)。可以发现,由于准循环LDPC是由部分基础矩阵来定义的,所以,这些使用中的准循环LDPC码的缺点都是灵活性不足,所述的灵活性是指编码码率和编码码长灵活变化。在新无线接入技术(new Radio Access Technology,简称new RAT)系统中,需要信道编码方案支持灵活码率码长,即支持信息长度起码达到和LTE系统一样甚至更低的颗粒度,以及码率可以灵活变化。例如,new RAT系统中包括如下应用场景:增强移动宽带(enhanced Mobile Broadband,简称eMBB)场景、超可靠低时延通信(Ultra-Reliable and Low Latency Communications,简称URLLC)场景或者大规模物联网(massive Machine Type Communications,简称mMTC)场景中。其中eMBB场景中下行最大吞吐量可以达到20Gbps,上行数据最大吞吐量可以达到10Gbps;以及在URLLC中,可以支持可靠性最低达到10e-5的BLER(Block Error Rate)以及上下行达到最短时延达到0.5毫秒;以及mMTC能使设备电池可以使用多年不断电。
但是,LDPC码对于各个应用场景的适应性存在问题,例如高吞吐量场景 和低吞吐量场景,大覆盖要求和小覆盖要求,以及不同工作模式的要求。针对相关技术中LDPC码适应性问题,目前还没有有效的解决方案。

在一种实施方式中,所述准循环LDPC编码包括Y个基础矩阵,依据所述表征信息比特序列的数据特征从所述Y个基础矩阵中选择出1个基础矩阵进行准循环LDPC编码,获得LDPC编码序列,Y是大于1的整数。
所述Y个基础矩阵至少包括以下特性之一:
1)所述Y个基础矩阵中存在模板矩阵相同的至少2个基础矩阵,所述模板矩阵相同是指:2个基础矩阵为M1和M2,所述M1的模板矩阵等于所述M2的模板矩阵,且所述2个基础矩阵中至少存在1个非-1元素值不相等;所述模板矩阵是将基础矩阵中的非-1元素位置赋值为“1”以及-1元素位置赋值为“0”所获得的矩阵。所述模板矩阵相同特征的有益效果是:基础矩阵之间存在嵌套特性,使得准循环LDPC译码器的结构更为统一,软信息存储和读取路由统一,译码器更为紧凑简单。
2)所述Y个基础矩阵中存在模板矩阵准相同的至少2个基础矩阵,所述模板矩阵准相同是指:2个模板矩阵有a个元素不同,所述a是大于0且小于或等于10的整数,例如,2个基础矩阵为M3和M4,所述M3的行数等于所述M4的行数,所述M3的列数等于所述M4的列数,所述M3中的所有非-1元素所对应的行列索引号对所构成的集合为SET3,所述M4中的所有非-1元素所对应的行列索引号对所构成的集合为SET4,其中,所述集合SET3与集合SET4的差集为DS3,所述DS3的元素个数小于或等于TH3,所述集合SET4与集合SET3的差集为DS4,所述DS4的元素个数小于或等于TH4,其中所述TH3和TH4是小于10的正整数。

3)所述Y个基础矩阵中存在矩阵元素准相同的至少2个基础矩阵,所述矩阵元素准相同是指:2个基础矩阵中有b个元素不同,所述b是大于0且小于或等于10的整数;例如,2个基础矩阵为M5和M6,至多TH5个行列索引号对,所述M5中由所述行列索引号对所索引的元素不等于所述M6中由相同所述行列索引号对所索引的元素;所述模板矩阵是将基础矩阵中的非-1元素位置赋值为“1”以及-1元素位置赋值为“0”所获得的矩阵,TH5是小于10的正整数。所述矩阵元素准相同特征的有益效果是:可以使得准循环LDPC译码器中的交织网络依然很统一,虽有部分元素不同但是对增加的复杂度影响不大,译码器简单容易设计。在如图10(a)和图10(b)所示的基础矩阵示例中,TH5=2,其中TH5=2个行列索引号对为[1,0]和[0,1]。当然模板矩阵也可以在不同情况下的2个基础矩阵也可以存在矩阵元素准相同的特性。
4)所述Y个基础矩阵中存在模板矩阵嵌套的至少2个基础矩阵,所述模板矩阵嵌套是指:所述模板矩阵嵌套的2个基础矩阵中,小基础矩阵的模板矩阵是大基础矩阵的模板矩阵的一个子矩阵,例如,2个基础矩阵为M7和M8,所述M7的行数小于所述M8的行数,所述M7的列数小于所述M8的列数,所述M7的模板矩阵是所述M8的模板矩阵中的一个子矩阵。所述模板矩阵是将基础矩阵中的非-1元素位置赋值为“1”以及-1元素位置赋值为“0”所获得的矩阵。所述模板矩阵子集相等特征的有益效果是:在不同基 础矩阵大小情况下,小基础矩阵是大基础矩阵的子集,即小基础矩阵嵌套在大基础矩阵中,可以使得准循环LDPC码译码器的具有兼容性,采用同一个译码器就可以实现不同基础矩阵大小的译码,译码简单方便设计。如图11所示,基础矩阵(a)(如图11(a)所示)是基础矩阵(b)(如图11(b)所示)的一个子矩阵。
5)所述Y个基础矩阵中存在模板矩阵子集相等的至少2个基础矩阵,所述模板矩阵子集相等是指:基础矩阵1的模板矩阵中存在一个子矩阵等于基础矩阵2的模板矩阵中的一个子矩阵,例如,2个基础矩阵为M9和M10,所述M9的行数小于所述M10的行数,所述M9的列数小于所述M10的列数,所述基础矩阵M9和M10都存在以下结构:
