OFDM水声通信系统信道估计算法应用研究
摘要
Abstract
The precision and validity of channel estimation are the assurance of OFDM(Orthogonal Frequency Division Multi-plexing)underwater acoustic communication system with good performance. LS-MP(Least Square, Matching Pursuit)channel estimation algorithm based on Compressive Sensing(CS)is studied using the sparsity of the underwater acoustic channel, after the research of the LS and LMMSE(Linear Minimum Mean Square Error)channel estimation algorithm. And the simulink with LS, LMMSE and LS-MP baed on CS in OFDM underwater communication system is done respectively. The performance of these algorithms is analyzed and compared.关键词
