Abstract :
The performance of the MUSIC algorithm in the presence of channel mismatch is studied. Theoretical expressions for the error in the MUSIC DOA estimates and Cramer-Rao bound are derived. These are compared with simulations performed for some representative cases. The theoretical results and simulation show that the existence of channel mismatch will increase the error of DOA estimates and seriously degrade its performance
