  • Orthogonal Frequency Division Multiplexing (OFDM) has been currently under intense research for broadband wireless transmission due to its robustness against multi-path fading. However, OFDM signals are characterized by large peak-to-average power ratios (PAPR), which can reduce the system efficiency. To overcome this problem, in this paper, based on the definition of the PAPR in OFDM systems, we will mainly investigate the PAPR reduction performance with two different PAPR reduction methods… CONTINUE READING
