Interference Processing for Multi-User Wireless System
This paper deals with the exploitation of Multiple Input Multiple Output (MIMO) systems for broadband wireless indoor applications. More specifically, multiple access channels with multiple antennas are considered. Aiming to improve the system performance, an interference cancellation scheme is proposed to eliminate the interference for each user. In this paper, the authors derive a scheme that could be used for any number of users with any number of antennas. The decoding complexity is the lowest and the diversity gain is the highest with similar configuration. Computer simulation results show the effectiveness of the interference cancellation scheme based on MIMO systems.
