An efficient method for blind digital signal separation of array data

Abstract The paper deals with the problem of blind separation of multiple co-channel digital signals received by an antenna array. An efficient method based on the use of the symmetric property possessed by the received array data is proposed to significantly improve the performance of the approach previously presented in Anand et al. (1995). Moreover, the required computational complexity using the proposed method is reduced as compared to that using the conventional methods. The effectiveness of the proposed method is confirmed by computer simulation results.
