Comments on 驴Blind Calibration and DOA Estimation With Uniform Circular Arrays in the Presence of Mutual Coupling驴

摘要

Comments on a paper by Lin and Yang (IEEE Antennas Wireless Propag. Lett., vol.5, p.315-18, 2006). A modification of the proposed algorithm is suggested for better numerical stability and less computation load. The overlooked parameter identifiability problem of the proposed algorithm is discussed in detail. Besides, solution to the ambiguous DOA estimates is also proposed
