Iteration interference cancellation decoding for multi-user MIMO uplink transmission system

Abstract

In this paper, an iteration interference cancellation detector for multi-user MIMO uplink transmission system is proposed, which utilizes the special property of Orthogonal Space Time Block Code(OSTBC) equivalent channel of each user to simplify the decoding at the base station. With the proposed algorithm the number of receive antennas is significantly reduced as much as the number of users, and more spatial multiplexing gain can be obtained. Simulation results validate our proposed algorithm in terms of BER performance.
