Abstract

Under non-uniform white noise, a novel DOA algorithm was proposed. Firstly, the likelihood function of unknown parameters of noise and estimated signals was given. Then, the iterative method was used to make the algorithm converge in a stepwise way and the estimated parameters were got. In addition, a new method was proposed to estimate the parameters of noise. The theoretical analysis and computer simulation show that the performance of proposed algorithm is better than that of conventional maximum-likelihood DOA estimation algorithm in the presence of non-uniform white noise, and its complexity is not too high.

Key words： DOA estimation; maximum-likelihood algorithm; non-uniform white noise; RMSE
