| Abstract: | The wavelet packets-based MUSIC (WP-MUSIC) is proposed in this paper to improve the performance of classical MUSIC in scenarios of closely spaced DOA and low signal-to-noise ration (SNR) Scenario. The computation loads of WP-MUSIC is proven superior to MUSIC. The WP-MUSIC is to decompose the fullband signal into several subbands by wavelet packets, and then apply MUSIC on each subband. Some simulation results, proving the validity and improved performance of the proposed approach, are presented. | ||
