The Viterbi algorithm is the same as the binary case with one main difference: The survivor sequences include the uncoded bits, which are decided at each TRELLIS stage when selecting one of two parallel branches with the largest correlation metric. Presently, only 8-PSK modulation is considered. Extensions to higher-order modulations can be implemented following a similar procedure.

[LDPC码]是LDPC码相关论文 [WuYuFei]中是WuYuFei的论文 [WuYufei_matlab]是WuYufei做Turbo码的Matlab程序 程序实现在固定信噪比和卷积长度的条件下,计算不同正常的帧错误概率和比特错误概率 turbo_sys_demo.m是主程序 其中TRELLIS.m是构造网格的子程序 logmapo.m是LOGMAP译码算法子程序 sova0.m是SOVA译码算法子程序 encoderm.m是编码子程序 [22]是以WuYufei程序的改动,实现在帧长、信噪比和迭代次数固定的情况下,获得两个译码器的先验信息的变化情况 http://www.pudn.com
