Performance Analysis of Low-Complexity System for PAPR Reduction in OFDM Communication System

Abstract

To reduce the peak OFDM signals that can be distorted by the nonlinearity of power amplifiers, this project has proposed an efficient structure for implementing the tone reservation method that assigns appropriate data to reserved tones. In the proposed structure, a new binary search algorithm is proposed for the peak OFDM signal Clipping, and the FFT is replaced with an approximate DFT in which complex multiplications are replaced with shift operations.The proposed system is simulated using modelsim and syntheized in Xilinx project navigator.
