DOA estimation of correlated wideband signals by using multi-band EM algorithm

Summary form only given. Direction-of-arrival (DOA) estimation problem for wideband signals with an array antenna is considered in this report. History of the DOA estimation for wideband signal has several decades. Many techniques have been proposed. However, several problems still remains to be solved or to be developed to make use of wideband signal properties. Much more attention has been paid to wideband DOA estimation because of broadband communications based on the OFDM, UWB, and so forth.
