The most widely used multiplexing technique in present wireless communication scenario is Orthogonal Frequency Division Multiplexing. PAPR is one of the most challenging observation and problem in the signals which are transmitted in the system. Different optimization techniques are been proposed to reduce PAPR. In this paper, SLM combined with grey wolf optimization technique is proposed and the results are been compared with other SLM based optimization techniques like SLM-GA, SLM-FA. The PAPR reduction accuracy and the level of complexity have been reduced using the proposed approach. The proposed model is simulated using Matlab software tool.
