Abstract :
A study of the characteristics of the MUSIC and the modified forward-backward linear prediction (MFBLP) methods of angle-of-arrival estimation, in terms of their sample bias and resolution in the fully correlated signal environment, is presented. Using Monte Carlo simulations, it is shown that the MFBLP algorithm has better capability in resolving two fully correlated signals than the spatially smoothed MUSIC algorithm
