Abstract: It is shown in [1] that when all the incoming signals are sent by non-circular AM/BPSK sources, the DOA estimation accuracy as well as the maximum number of detectable signals can be dramatically increased. However, it is more realistic that some users send non-circular symbols while other users still send circular symbols. In this paper, we develop an algorithm to cope with this more general scenario. The proposed algorithm can still make use of the existing non-circular signals to increase the maximum number of detectable signals as well as to improve the performance accuracy compared to the conventional MUSIC algorithm. Moreover, the spatial smoothing technique related with the new model is developed. The results of the computer simulations clearly show the effectiveness of our proposed algorithm.
