Naveena Choudhary, Karuna Markam

Abstract


Orthogonal frequency division multiplexing (OFDM) is successfully used as a part of various developed correspondence system over multipath channels. One of the significant drawbacks of OFDM is the occurrence of high peak-to-average power ratio (PAPR). OFDM signals are very sensitive to nonlinear effects due to high PAPR, which stimulate the power inefficiency in the RF range of the transmitter. The present paper is focused on finding the PAPR diminish by undertaking distinctive procedures to decrease the PAPR in the method PTS, companding and a combination of PTS and companding, simulation results comes about utilizing neural network demonstrates that the proposed strategy defeats different strategies for PAPR reduction.
