Abstract :
An algorithm that combines the signal selectivity of cyclic MUSIC with the ability to function well in the presence of fully correlated multipath is presented. Analytical results and computer simulations are presented to support the claims, which include the ability to estimate directions of arrival of desired signals in the presence of multipath and arbitrary numbers of arbitrarily closely spaced interfering signals. Furthermore, the algorithm can estimate the number of spectrally correlated signals with any particular cycle frequency, and it implicitly obtains maximum signal-to-interference-plus-noise ratio (SINR) estimates of those signals
