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 code is a class of easy to achieve high-speed iterative hardware decoding block code. The iterative decoding algorithm of soft input soft output of Turbo product code is analyzed. Combining the Turbo product code with the QAM modulation, a simplified scheme of joint demodulation and decoding for hardware implementation is proposed. Simulation results show that this simplified scheme has little effect on the decoding performance.
