摘要: For a single signal, numerical comparison of the Bayesian Cramer-Rao lower bound, Chazan-Ziv-Zakai bound and Weiss-Weinstein on DOA estimation MSE shows that CZZLB is tightest can accurately predict threshold SNR, which critical system design parameter. The analysis extended to two signals where multiple parameter WWLB applicable but appears be weak bound. Simulation results show below maximum likelihood procedure such as Expectation Maximization(EM) algorithm seeded by Alternating Projection Maximization (APM) should used provide best performance. Above use statistically efficient MUSIC adequate.
