Abstract :
A low complexity method for signal subspace fitting is proposed. The novel signal subspace used in the method is spanned by the pre-filters of the multi-stage Wiener filter. Studies and simulations have shown that, when the incident signals are coherent, the new method achieves comparable results with the weighted subspace fitting estimator but requires much lower computational cost.
