Chapter 19 Particle Swarm Optimisation Aided MIMO Transceiver Designs

Abstract. Multiple-input multiple-output (MIMO) technologies are capable of sub-stantially improving the achievable system’s capacity, coverage and/or quality of service. The system’s ability to approach the MIMO capacity depends heavily on the designs of MIMO receiver and/or transmitter, which are generally expensive op-timisation tasks. Hence, researchers and engineers have endeavoured to develop effi-cient optimisation techniques that can solve practical MIMO designs with affordable costs. In this contribution, we demonstrate that particle swarm optimisation (PSO) offers an efficient means for aiding MIMO transceiver designs. Specifically, we con-sider PSO-aided semi-blind joint maximum likelihood channel estimation and data detection for MIMO receiver, and we investigate PSO-based minimum bit-error-rate multiuser transmission for MIMO systems. In both these two MIMO applications, the PSO-aided approach attains an optimal design solution with a significantly lower complexity than the existing state-of-the-art scheme. 19.
