The peak-to-average power ratio (PAPR) of a transmitted signal is one of the major challenges in multi-carrier broadband systems using OFDM (orthogonal frequency division multiplexing) or multiple output multi-input (MIMO) OFDM. Understanding the effects of PAPR on OFDM and MIMO-OFDM systems is critical in determining which techniques to use to improve system performance. For the purposes of this blog post, we can use the terms OFDM and MIMO-OFDM interchangeably without affecting the meaning of PAPR.
Peak to Power Average (PAPR) is one of the serious problems in any wireless communication system using the multi-carrier modulation technique such as OFDM, which reduces the efficiency of the high-power transmission amplifier. In this paper, a proposed scheme will be presented that will combine the intercalation method with the window peak. The simulation results show that our technique simultaneously decreases bit error rate (BER), reduces PAPR by 3.5 dB and improves external band radiation in the presence of a nonlinear power amplifier model.
