RESEARCH ON FOC- MUSIC ALGORITHM OF VIRTUAL UNIFORM LINEAR ARRAY FOR WIRELESS LOCATION BASED ON TD-SCDMA

摘要

DOA estimation is very important in the circle-angle location based on smart antenna of TD-SCDMA. In the paper, In consideration of the small array aperture and poor robustness of the disturbed array errors for MUSIC algorithm based on the virtual uniform linear array in mode space, the 4-order cumulant MUSIC (FOC-MUSIC) algorithm based on the virtual uniform linear array in mode space are proposed, and it's performance is analyzed.
