| Abstract: | An array signal model exploiting first order cyclostationarity of source signals is presented in this paper. According to the model, an efficient approach to estimate the DOA for source signals using LS method is developed. The comparison is made with MUSIC algorithm to show its better performance. For the cases of single and multiple objects, simulations are made and the results indicate the efficiency of the given method. |
