Direction of arrival estimation based on the MSWF
WU Shun-junn · Journal of Xidian University · 2004
Utilizing the reduced-rank technique of the Multi-Stage Wiener Filter(MSWF), a novel method for Direction Of Arrival(DOA) estimation is proposed, resulting in a new way for parameter estimation. Analysis and simulation show that this method can be applied in the case where only a few samples are available and the Signal to Interference plus Noise Ratio (SINR) is very low. On the other hand, the new method requires much lower computational cost than the subspace-based methods. Finally, simulations are given to validate the method.
