| Abstract: | DOA estimation is very important in the circle-angle location based on smart antenna of TD-SCDMA. In the paper, Considering that MUSIC algorithm for virtual uniform linear arrays in mode space can not be used to estimate DOA for correlated signals, the modified MUSIC algorithm (MMUSIC) based on virtual uniform linear arrays in mode space is proposed. Then, the problem for DOA estimation of correlated signals has been resolved, and it's performance is analyzed. |
| Keywords: | time division-synchronization code division multiple access (TD-SCDMA) modified multiple signal classification (MMUSIC) virtual uniform linear array direction of arrival (DOA) |
