摘要
基于交织多址网络编码中继合作系统,分析了其采用Turbo编码后在多径信道环境下的系统性能。研究了该系统中利用不同交织器来实现多用户的多址接入方式以及网络编码的中继合作机制。将多径信道以及Turbo编码融入该系统中,搭建计算机仿真环境,通过仿真数据分析系统性能。仿真结果表明,在多径信道环境下,采用Turbo编码的交织多址网络编码中继合作系统的系统误码率有明显改善。
Based on network coding relay cooperative Interleaver Division Multiple Access（IDMA） system,the performance of the system with Turbo code in multi-path channel is analyzed.The multiple access method of adopting different interleavers for different users and the network coding relay cooperative mechanism are studied,the multi-path channel and Turbo code are added into the system to establish simulation environment.The simulation results show that in the multi-path channel,Turbo code has improved the BER performance of network coding relay cooperative IDMA system greatly.
