Abstract
An Arrangement of using OFDM system with multiple input multiple output (MIMO) System provides excellent performance against Multi path effects and frequency selective fading. However, the high PAPR is the one of the significant downside of OFDM framework to send the signals on various antennas. In this study, an exhaustive review of the PAPR in wireless 4G OFDM communication systems has been explored, and an enhanced partial transmit sequence, cooperative partial transmit sequence, and ZCT precoded and postcoding PAPR reduction technique-based system has been provided. The suggested approach greatly enhances communication system performance, as demonstrated by CCDF curves for various modulation parameter test scenarios. In this proposed work 512 numbers of subcarriers are carryout in the length of 1024 and 100 numbers of frames in AWGN channel.
