Abstract
Cyclostationarity has been introduced to direction of arrival (DOA) estimation due to its immunity to interference and noise. In this paper, we propose a MUSIC-like DOA estimation algorithm which can be applied to wideband cyclostationary signals. By exploiting both cyclic and cyclic conjugate correlations, the new algorithm not only applies to wideband signals, but the performance is also substantially improved. Furthermore, under certain conditions, the new algorithm can detect DOAs of more wideband sources than the number of antennas simultaneously. Simulations confirm the theoretical findings.
