Abstract: The direction of arrival estimation (DoA) can be improved by extending the search of the angle to the complex space. In particular, the MUltiple SIgnal Classification algorithm for DoA estimation is clearly enhanced if the usual search of the angle is extended to the complex plane. Furthermore, this approach can be used even in really adverse conditions such as low SNR, small number of snapshots, or when the direction of arrivals is very close.
