摘　　要：推出了一种新型的纠错码——Turbo乘积码(TPC),描述了Turbo乘积码的编译码基本思想,详细地分析了TPC的Turbo软迭代译码的核心思想,并对AWGN信道和瑞利衰落信道下的TPC的译码性能做了仿真分析,从仿真结果可以看出,在高编码效率时,TPC不仅具有更高的码率,而且可以获得很好的误码率性能,所以乘积码的软迭代译码方案有很好的应用性,在未来的宽带移动通信中具有广阔的应用前景。This paper presents Turbo Product Code（TPC） for forward error correction coding. It describes the basic ideas of both encoding and decoding,and particularly analyses the key ideas of Turbo iterative decodeing of TPC,compares the simulation performance of TPCs on the Gaussian channel and on the Rayleigh channel The results show that TPC has a better performance at a higher code rate,TPC can achieve better Bit Error Rate（BER）with a higher code rate, so TPC solution is more attractive for the broadband wireless access system in future.
