PAPR and BER performance of OFDM with Various Modulation Methods under AWGN Channel

The Orthogonal Frequency Division Multiplexing (OFDM) is also known as multicarrier technology. Wideband digital communications in the recent past have increasingly utilized OFDM. It can withstand difficult channel circumstances, efficiently utilize spectrum resources, decrease ISI, and operate at a high data rate, among many other benefits. has been used several wireless wired communication systems, including fourth generation Long-Term Evolution (4G LTE) mobile communications. performance assessment analysis of OFDM system under Additive White Gaussian Noise (AWGN) carried out this work. factors which assessed include signal quality, Bit Error Rates (BERs), Signal to Ratios (SNRs) received signals. To improve while employing modulation, subcarriers must be kept orthogonal one another, process sole focus study PAPR, BER, SNR utilizing various modulation methods schemes.
