Modified subspace algorithms for DOA estimation using MIMO array
Jianguo Huang, Lijie Zhang, Yunshan Hou, Yong Jian Jin · 2008
This paper proposes two subspace algorithms, named S-MUSIC and S-SSMUSIC, based on the MUSIC and SSMUSIC algorithms for direction finding in MIMO array systems, which achieve improved performance by exploiting the waveform information about the transmitted signals. Numerical results show that the proposed algorithms outperform their traditional counterparts at low SNR.
