摘　　要：近年来,人们对于自编码在扩频通信系统中应用进行了大量研究并取得丰富成果。文章将自编码技术引入TH-BPSK UWB系统,并在接收端用迭代检测代替维特比译码算法,大大降低接收设备复杂性。大量仿真结果表明,该方法能降低数据接收的误码率和接收端设备复杂性,提高系统的接收性能。In general, repetition encoded is employed in traditional UWB system. In recently years, people have paid much attention to the research of self-encoded in the spread spectrum communication system and gotten certain achievements. This paper employs self-encoded in TH BPSK UWB system, as well as iterative detection instead of Viterbi decoding algorithm in the receiver, which not only improves the system performance but also reduces the receiver＇s complexity. The simulation results show the advantages of the system.
