摘　　要：Turbo乘积码(TPC)是一种性能优异的前向纠错编码技术。卫星ATM技术代表了卫星通信网络的研究方向。研究了TPC在卫星ATM系统中的应用方案。首先,分析了卫星信道对ATM信元传输带来的影响;然后对TPC的编、解码的方法进行了简要介绍,并阐述了TPC的优越性能;最后,提出了一种卫星ATM网络中应用TPC的解决方案,并通过仿真得到了该方案的性能曲线。仿真结果证明,TPC的应用能够大幅降低卫星信道的误码率,使ATM信元能够正确传输。Turbo product code （TPC） is a kind of forward error correct code with excellent performance. Satellite ATM technology represents the research trends of satellite communication networks. This paper studied the application of TPC in satellite ATM systems. At first, the characteristics of satellite communication and their impact on the transfer of ATM cells are analyzed; then the coding and decoding methods of TPC and their excellent performance are introduced; finally, the method that the TPC is applied in satellite ATM networks is presented and the results of simulation are obtained. The decline of bit error rate in the satellite communication and the correct transfer of ATM cells are verified by the result of the simulation.
