COCHANNEL SIGNAL RECOVERY USING THE MUSIC ALGORITHM AND THE CONSTANT MODULUS ARRAY

In this letter, we describe an approach to cochannel signal recovery f or correlated sources that is based on the MUSIC (multiple signal clas sification) algorithm and the constant modulus (CM) array. The MUSIC a lgorithm provides estimates of the source angles of arrival, which are used to initialize a parallel bank of CM arrays. These adaptive beamf ormers are updated by the constant modulus algorithm (CMA) to capture and track the source signals, even when they are highly correlated. Co mputer simulations are presented to illustrate the transient behavior of the proposed algorithm.
