摘　　要：对三维TPC(Turbo乘积码)编译码的算法及性能进行了仿真。TPC编码的3个子码都采用(16,11)的扩展汉明码,编码码率约为0.32,码字长度为4096。三维TPC译码采用基于Chase2算法的软输入/软输出迭代译码算法。利用matlab进行仿真,采用4次迭代,在AWGN信道中,Eb/NO为3dB时,误码率小于1×10-6。这种纠错方式适用于带宽宽,功率受限且传输性能要求高的通信系统中。The algorithm and performance of a three-dimensional Turbo product code （TPC） codec are emulated. The three component codes of TPC code use of extended hamming codes （16, 11） of which the code rate is about 0.32 and code length is 4096. The three-dimensional TPC Becoder use soft： input/soft output iterative decoding based on Chase2 algorithm. In the emulation with matlab, four iterations are adopted and bit error rate is less than 1×10^-6 with Eb/N0 is 3dB in the channel of Additive White Ganssian Noise （AWGN）. The communication system with wide bandwidth, limitative power and high performance required in transmission is applicable in using the foreword error-corrected codes.
