In this paper, the authors proposed a Particle Swarm Optimization (PSO) based Partial Transmit Sequence (PTS) technique in order to achieve the lowest Peak-to-Average Power Ratio(PAPR) in Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems. their approach consist of applying the PSO based PTS on each antenna of the system in order to find the optimal phase factors, which is a straightforward method to get the minimum PAPR in such a system. The simulation results demonstrate that the PSO based PTS algorithm when applied to MIMO-OFDM systems with a wide range of phase factors, tends to give a high performance.
