Comparative Analysis of Clipping-filtering, SLM and PTS for PAPR Reduction Technique in OFDM System
Modulation scheme, orthogonal frequency division multiplexing (OFDM) uses multiple carriers to communicate and transmit data. It is used widely in wireless communication due to its numerous advantages. OFDM modulation is very advantageous as it reduces inter symbol interference, provides high data rate and it is not affected by narrow band effect. To operate OFDM effectively, its high value of peak to average power ratio should be reduced. In OFDM, power amplifier should be linear and accommodate amplitude variations to work efficiently. The high peak to average power ratio affects the performance of power amplifier.
