摘要
Turbo乘积码是一类易于硬件实现高速迭代译码的分组码。对Turbo乘积码软输入软输出迭代译码算法进行了分析。将Turbo乘积码与QAM调制结合起来,提出了一种简化的、便于硬件实现的联合解调译码方案。仿真结果表明这种简化方案对译码性能影响很小。
Turbo product codes are belong to block code, and whichcan be decoding by hardware with high speed comparing to parallel concatenated convolution codes. By studying soft-in soft-out iterative decoding algorithmof turbo product codes, Combining with QAM modulation, we give a joint demodulation and iterative decoding algorithm which is simply and easy to implement by hardware. Results of simulation show that performances of decoding suffer a little from this simplified scheme.
