基于压缩感知的NC-OFDM系统的BAOMP算法的信道估计*
Compressing sensing based BAOMP algorithm channel estimation in NC-OFDM system
摘要
Abstract
This paper is based on the lately rising compressing sensing theory , studying channel estimation for NC-OFDM sys-tem and using BAOMP algorithm to NC-OFDM system ’ s channel estimation . It detects the previous chosen atoms ’ reliability and then deletes the unreliable atoms at each backtracking iteration . Simulation and theoretical analysis shows that BAOMP algorithm can reduce the pilots number . Besides , BAOMP not only has the advantages of the OMP-type but also has superior performance of signal construction . Besides , it doesn ’ t need to know the sparsity level K .关键词
