| Abstract: | Many man-made signals encountered in communications, such as BPSK, FSK, AM signals, exhibit cyclostationarity. By exploiting the cyclostationarity, Cyclic MUSIC has been shown to be able to separate the signals with different cycle frequencies, thus, to be able to perform signal selective Direction of Arrival (DOA) estimation. However, both Cyclic MUSIC and the conventional MUSIC suffer performance deterioration when the signals are either wideband or coherent. In this paper we propose a new method that combines the Spatial Smoothing (SS) method with a revised Cyclic MUSIC named Averaged Cyclic MUSIC. Simulation results show the effectiveness of the proposed method in signal selective DOA estimation for wideband signals under a multipath environment. | ||
