论文摘要
使用硬否决解码和内部单个奇偶校验检查（SPC）代码，使用Chase/Wagner Soft-Decision解码来研究串联的正向误差校正。分析表达式是针对端到端框架的分析表达式，使用二进制相移键合（BPSK）和第四纪振幅偏移键（4- ass）以及符号交织者和量化通道输出的二进制相移键合（BPSK）和第四纪振幅偏移键（4- ass）和Quaternary振幅偏移键（4- ass）的传输率。将BPSK错误率与其他两个内部代码的错误率进行了比较：带有SPC组件代码和扩展锤子代码的二维产品代码。还提出了单位内存符号间干扰通道和4个sask的仿真结果。结果表明，编码方案达到了相似的错误率，但是SPC代码的复杂性最低，并且允许柔性速率适应。
Concatenated forward error correction is studied using an outer KP4 Reed-Solomon code with hard-decision decoding and inner single parity check (SPC) codes with Chase/Wagner soft-decision decoding. Analytical expressions are derived for the end-to-end frame and bit error rates for transmission over additive white Gaussian noise channels with binary phase-shift keying (BPSK) and quaternary amplitude shift keying (4-ASK), as well as with symbol interleavers and quantized channel outputs. The BPSK error rates are compared to those of two other inner codes: a two-dimensional product code with SPC component codes and an extended Hamming code. Simulation results for unit-memory inter-symbol interference channels and 4-ASK are also presented. The results show that the coding schemes achieve similar error rates, but SPC codes have the lowest complexity and permit flexible rate adaptation.
