The Genetic Algorithm in the Minimum Bit Error Rate Multi-User Detection Assisted Space Division Multiple Access System

This is a recent research on Space Division Multiple Access-Orthogonal Frequency Division Multiplexing (SDMA-OFDM) based on the biological technique of Genetic Algorithm (GA) which is reminiscent of the rules of evolution and survival where a group of fitters´ individuals in a population will survive more and more using in the wireless communication in the Multi-User Detection. The goal of this research is using Genetic Algorithm assisted by Minimum Bit Error Rate (MBER) comparatively of the Conjugate Graduate (CG) method to Multi-User Detection on OFDM due to the technique using the symbol chromosomes to obtain an initial Frequency Domain-Channel Transfer Function (FD-CHTF) assisted by Minimum Bit Error Rate that the GA is capable of approaching the MBER solution at a lower complexity than the CG algorithm and it can be achieved by the simulation results provided to demonstrate the improvement of Multi-User Detection using Genetic Algorithm assisted by Minimum Bit Error Rate.
