Power and DOA Estimation for Array Processing with DFP and BFGS Algorithm

To increase the capacity of mobile communications, it is important to accurately estimate the power and the directions of arrival (DOA) of sources. An efficient algorithm is proposed for this purpose with Davidon Fletcher Powell (DFP) and Broyden Fletcher Goldfarb Shanno (BFGS) algorithm. To estimate DOA and power of sources, the method optimizes the DOA and power parameters of a cost function simultaneously with DFP&BFGS Algorithm. The simulation results show that the proposed algorithm can simultaneously estimate the DOA and powers of signals accurately.
