EVALUATION OF PAPR REDUCTION ABILITY OF 5G INSPIRED WAVEFORM CANDIDATES

The multifold increase in multimedia technology triggers an insatiable thirst for high data rates and increased demand for Orthogonal Frequency Division Multiplexing based wireless systems, a superior technology for the high-speed wireless communication systems. OFDM technique possesses multiple benefits superior to its predecessor, namely, its high capacity and resistance to multipath fading channels. Nonetheless, few hurdles remain yet unresolved in OFDM systems. The foremost issue stands out to be the high Peak to Average Power Ratio, which results in non-linearity in the High-Power Amplifiers and drives In-Band Distortion and Out-Of-Band Emission. Research plans are currently under development to standardize, given the economic 5G boom for market commercialization. The rise of superior waveform competitors possessing higher spectrum throughput, lower Peak to Average Power Ratio having a more straightforward system design than the celebrated OFDM. Potential candidates include numerous single carrier and multi-carrier waveforms. This paper undertakes an assessment, highlights the strengths and weaknesses of various 5G waveform candidates under the Key Performance Indicators, Simulation is carried out to study the PAPR reduction capabilities of these waveforms.
