Abstract :
Recently Multi User MIMO has been becoming an interesting topic in wireless communication system. Vector Perturbation can achieve near capacity, but it has high complexity which makes it is difficult to be implemented in the hardware. In this paper we propose an algorithm to reduce the complexity of the Vector Perturbation with negligible decrease in performance.
