Wideband cyclic MUSIC algorithms

In this paper, we propose two cyclic-MUSIC-like DOA estimation algorithms for wideband cyclostationary signals, the averaged cyclic MUSIC (ACM) algorithm and the extended wideband cyclic MUSIC (EWCM) algorithm. Compared with the existing spectral correlation signal subspace fitting (SC-SSF) algorithm, which was also developed for wideband cyclostationary signals, our new methods have more relaxed requirements on the signals. Simulation results show that under those circumstances, both our methods are superior to the existing SC-SSF algorithm.
