Description
技术领域
本发明涉及数字信息传输领域,具体涉及一种基于[255,16,112]循环码的强纠错编码方法。
背景技术
在数字通信系统中,特别是无线数字通信系统中,发射机与接收机之间的通信信道会受到随机噪声的干扰,这会在所传递的信息中引起错误。处理这个问题的一种方法是使用纠错编码。纠错编码是将冗余信息添加到消息传输中,使接收机能够在一定程度上纠正信息在信道上传输时发生的误码。
常见的纠错编码方法包括BCH码、RS码、低密度奇偶校验码、Turbo码、卷积码等。不同的纠错编码方法具有不同的纠错性能,也有不同的适用场景。在具体应用中,需要根据应用场景选择适合的纠错编码方法,并进行具体的优化处理。
发明内容
本发明要解决的技术问题是:提供一种基于[255,16,112]循环码的具有高纠错性能的编码方法。
本发明是通过以下技术方案实现的:第一步,将信息数据分割为以16比特为长度的信息码字,每个信息码字对应的码多项式表示为m(x)=m15x15+m14x14+…+m0,其中多项式系数mi(i=0,1,…15)为信息码字相应比特位的值;第二步,确定循环码生成多项式g(x)为:g(x)=x239+x234+x231+x230+x229+x227+x226+x224+x220+x219+x218+x217+x213+x212+x210+x207+x202+x201+x197+x195+x194+x191+x187+x185+x184+x180+x178+x177+x174+x171+x170+x168+x167+x166+x162+x160+x159+x158+x157+x156+x154+x153+x152+x144+x143+x141+x140+x137+x136+x135+x134+x133+x129+x124+x120+x118+x110+x109+x107+x106+x102+x101+x100+x99+x98+x94+x93+x91+x88+x86+x83+x82+x81+x77+x75+x74+x73+x72+x71+x68+x67+x64+x61+x60+x58+x57+x55+x54+x52+x51+x47+x44+x43+x42+x40+x39+x37+x35+x33+x32+x31+x27+x22+x16+x13+x10+x9+x7+x6+x4+x3+1;第三步,通过计算x239m(x)除以g(x),得到相应的余式r(x)=x239m(x)mod(g(x));第四步,根据上述结果,得到纠错编码对应的码多项式c(x)=x239m(x)+r(x)。
进一步,以上技术方案也可以通过[255,16,112]循环码生成矩阵G16×255实现编码,即[m15m14…m0]·G16×255=[c254c253…c0],其中[m15m14…m0]为16比特的输入信息码字,[c254c253…c0]为255比特的输出纠错编码码字。循环码生成矩阵G16×255由[255,16,112]循环码的典型生成矩阵G0经过模2线性行变换得到。[255,16,112]循环码的典型生成矩阵G0可表示为:G0=[I16Q16×239],其中I16为16阶的单位矩阵,Q16×239=(Q1Q2…Q16)T,其中,

进一步,为了适合计算能力受限的设备进行编码,可以将65536个所有可能的码字存储于设备中,以16比特的信息码字为地址,通过查找表的方式进行编码。
有益效果:
本发明的有益效果是:本编码方法采用[255,16,112]循环码的重量分布为:
循环码重量 | 0 | 112 | 120 | 128 | 136 |
出现次数 | 1 | 10200 | 4080 | 30855 | 20400 |
利用codetables(http://www.codetables.de)进行判断,本发明给出的[255,16,112]循环码属于最优循环码。同时,本纠错编码方法结合极大似然译码算法可以实现55位随机错码的纠错。
具体实施方式
以下结合优选实施例对本发明作具体的介绍。
作为优选,在模2运算的前提下,采用信息码字与[255,16,112]循环码生成矩阵G进行矩阵相乘的方式进行编码。此编码方式易于编程实现,并且可以以典型生成矩阵G0为基础,通过模2线性行变换得到不同的生成矩阵G,从而得到纠错性能一致的不同编码方案。
作为优选,以[255,16,112]循环码的典型生成矩阵G0为基础进行编码。输入信息数据分割为16比特的输入信息码字,表示为[m15m14…m0];典型生成矩阵可表示为G0=[I16Q16×239],其中I16为16阶的单位矩阵,Q16×239=(Q1Q2…Q16)T,其中,
