Abstract

The performance analysis of the MUSIC algorithm in the presence of channel frequency property mismatch is given. Theoretical relationships between the spatial spectrum and channel mismatch, and that between the resolution ability and channel mismatch are derived. The results show that the channel mismatch seriously degrades the MUSIC algorithm. The formulas were validated by computer simulation
