Temporal Side Manifold-A New Approach for Spatial Spectrum Estimation Using Temporal Informnation

Abstract

The present algorithms on 2-D temporal - spatial spectrum estimation are deteriorated when the number of signals become close to the dimension of the array. The expenses of the hardware and the software have to be increased to alleviate this degradation. In this paper, a kind of new signal model and approach for 2-D temporal - spatial spectrum estimation is proposed. Through the temporal projection, the maximal number of the signals this method can deal with is much more than present algorithms. Simulation results are presented to demonstrate the performance of the proposed algorithm.
