Multiuser detector based on constant modulus arrays applicable to MIMO systems

This paper proposes a novel blind multiuser detection scheme which can be applied for MIMO systems. Even though all algorithms employed are basically blind, the proposed scheme can not only separate each user´s signal but also achieve high transmission performance for each user without a priori information of a channel and transmit sequence. Especially, a correlation-based algorithm is proposed in order to avoid ill-convergence which sometimes happens in blind systems. Finally, performance of the proposed scheme is verified by computer simulation.
