Abstract
Multi-User Multiple-Input Multiple-Output (MU-MIMO) configuration is one of the most promising solutions to the fundamental problem of a telecommunication system: limited bandwidth. According to the MU-MIMO principles, different users transmit their signals concurrently at the same channel. It helps exploit channel capacity to a larger extent, but causes a harmful intra-channel interference at the same time. The receiver’s ability to combat the interference and retrieve individual users’ signals (Multi-User Detection, MUD) is a measure of the system dependability. In this paper we re-visit the solution to the MUD problem, based on the use of Genetic Algorithm (GA). The novelty of the current contribution is a re-designed method to generate the initial GA population, which improves the performance at no extra computational cost in comparison with the previous proposal.
