Abstract: The first issue of this paper is to make particle swarm optimisation (PSO) on partial transmit sequence (PTS) and clipping methods not simultaneously to get optimal phase factor sets using two sub-block partition and select the optimum level of clipping ratio respectively in order to lessen PAPR. Second issue is to make PSO of hybrid PTS with clipping (PSO-H-CPTS) which is used for the reduction in FBMC/OQAM system. The last issue is describe the joint optimisation between PSO and Cauchy mutation with the hybrid clipping and PTS techniques which is produce best result than other proposed algorithms, the experimental results shows that EPSO-H-CPTS improve the results by 71.5% than conventional traditional PAPR in both clipping and PTS where the PAPR reached to a value 2.9 dB after using joint optimisation hybrid techniques.
