Abstract

Major problems such as inter symbol interference (ISI), delay spread, doppler spread, and intercarrier interference may arise as a result of multipath signal transmission in wireless communication. In order to address these issues, OFDM technology with a cyclic prefix is employed. However, this comes at a price: a high peak-to-average power ratio (PAPR), which in turn increases the non-linear behaviour of the power amplifier. As a result, BER, in-band distortion, out-of-band emissions, and spectral efficiency are all negatively impacted. Over the previous few decades, several complicated PAPR reduction strategies have been presented. The aforementioned problems make OFDM technology unsuitable for 5G communications as it cannot meet the needs of next-generation wireless communication. We suggested a solution to the problems with OFDM, FBMC, and the 5G candidate waveform that would improve spectral efficiency while decreasing PAPR, out-of-band emissions, and latency. In order t
