Abstract
The Minimum Bit Error Rate (MBER) detector is capable of outperforming the conventional Minimum Mean Squared Error (MMSE) detector by minimizing the Bit Error Rate (BER) directly. In this paper, we proposed a hybrid Differential Evolution-Particle Swarm Optimization (DE-PSO) assisted MBER beamforming scheme for multipleantenna systems employed with Quadrature Amplitude Modulation (QAM) systems. The proposed hybrid scheme coalesced the merits of DE algorithm and PSO algorithm, meanwhile compensated the deficiencies of each other. Theoretical analysis and simulation results demonstrated that the proposed hybrid DE-PSO assisted MBER beamforming scheme outperformed the existing DE aided MBER beamforming scheme in converging speed.
