Abstract
Based on the analysis of bit interleaved coding broadband pulse modulation system in power line communication, this paper combines pulse modulation with direct sequence code division multiple access(DS-CDMA)to obtain orthogonal modula?tion and realize user multiplexing. The FD receiver signal processing algorithm is designed and the maximum likelihood frequency domain detector is deduced. The detector combines impulse noise with inter-symbol interference(ICI)and multiple access interfer?ence(MAI)generated by frequency. Simple hard feedback from channel decoder is used to improve channel frequency response and ICI-MAI noise-related estimation performance. The simulation results show that the scheme can expand symbol energy robustly through broadband pulse,spread spectrum code and bit interleaved convolutional code.关键词
