| 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，本文对单校验码为子码的高维Turbo乘积码的软输入软输出迭代译码算法进行了详细的分析。进而将其与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，充分利用了高维Turbo乘积码优越的纠错性能。仿真结果表明这种简化方案在高斯和衰落信道下的译码性能很好。

| Abstract: | Turbo product codes are a kind of block codes,which can be decoded at high speed by hardware.By studying soft-in and soft-out iterative decoding algorithm of turbo product codes especially those with single parity codes as subcode,combined with QAM modulation,we give a joint demodulation and iterative decoding algorithm which is simple and easy to implement in hardware.Results of simulation show that performance of this simplified scheme of decoding over AWGN and fading channels is fairly good. |
