Low complexity algorithm for PAPR reduction in OFDM system adopting SUI channel model

Ragini Yadav, Amit Goswami

Abstract


Orthogonal frequency Division Multiplexing (OFDM) is an attractive technology in Wireless Communication. High Peak-to-Average Power Ratio (PAPR) is one of the challenging issues in OFDM systems. High PAPR force the High Power Amplifier (HPA) to operate in its linear region with wide dynamic range, with poor power efficiency.

Index words: OFDM, Peak-to-Average Power Ratio (PAPR), SLM, High Power Amplifier (HPA).
