| Abstract: | This paper analyzes the statistic performance of the high resoution parameter estimation algorithm (MUSIC) in the presence of channel mismatch. The influence of Channel mismatch on spatial spectrum and the relationship between mismatch squaroerror and resolution ability are derived.The theory shows that the effect of channel mismatch on the performance of the algorithm is obvious.These formulas were validated by comuter simulation. |
