New signal model and approach for 2-D temporal-spatial spectrum estimation
Zheng Bao, Wang Yong-liang · Systems engineering and electronics · 2006
To solve the problem that the present 2-D temporal-spatial spectrum estimation algorithms are deteriorated when the number of signals become close to the dimension of the array,a kind of new signal model and approach for 2-D temporal spatial spectrum estimation is proposed.Though the temporal projection,the maximal number of the signals this method can deal with is much more than present algorithms with a small cost.Simulation results are demonstrate the performance of the proposed algorithm.
