Numerical Simulation and Meta Heuristic Design of Peak Average and Power Ratio Reduction Technique for 4th Generation OFDM Communication System

Abstract

Channel capacity and peak average to power ratio are two crucial factors in this rival wireless communication system that promise dependable communication across wireless medium. High peak to average power ratios have an impact on amplifier ratings in OFDM systems and prospective 5G system contenders like FBMC and UFMC. The growth of wireless network users is periodically driving up the demand for channel capacity. To increase the capacity of various fading channels, Multiple Input Multiple Output and Orthogonal Frequency Division Multiplexing (MIMO-OFDM) is a solid option. The power allocation technique is still used, though, and this limits the channel capacity. The Water Filling power allocation method determines the current channel capacity. The goal is to design an effective PAPR reduction method for the OFDM system based on an enhanced Partial Transmit Sequence (PTS). The water filling technique has also been used in the suggested research to offer capacity augmentation of the MIMO OFDM system for improving the effectiveness of the OFDM system. The suggested study has been contrasted with related modern algorithms like clipping and selective mapping. To visualize the effectiveness of the suggested method, capacity improvement strategies have also been contrasted. In the proposed system, there was an additional 5% reduction in peak average to power ratio and channel capacity. MATLAB is used to do a detailed analysis, and the results are then fully explored to gain a greater understanding of the dynamics of cooperative networks.
