自适应匹配追踪的OFDM系统窄带干扰检测
Narrow band interference detection for OFDM systems of the sparsity adaptive matching pursuit
摘要
Abstract
With orthogonal frequency-division multiplexing ( OFDM) , there is a problem with taking a long time to detect narrow band interference based on SAMP . This paper proposes an algorithm in which the adaptive matching pursuit algorithm is applied to the signal reconstruction of compressed sensing. The algorithm can automatically ad-just the number of atoms in the candidate set without knowing the prior information of the sparsity, and can realize the detecting single and multiple narrow band interference signals quickly below the Nyquist sampling rate. Simula-tion results show that the proposed algorithm can achieve the detection of narrow band interference accurately and has the merits of running faster which improves the performance of the OFDM communication system.关键词
