PAPR reduction in OFDM systems using higher order prediction filter

In this paper, a new scheme is proposed in Orthogonal Frequency-Division Multiplexing (OFDM) systems to reduce Peak-to-Average-Ratio (PAPR) without any influence on Bit-Error-Rate (BER). The high PAPR will leads to the non-linearity section in High Power Amplifier (HPA), which will degrade the performance and brings Inter Symbol Interference (ISI) in OFDM systems. In this paper, the high order prediction filter is implemented for reducing PAPR level in OFDM based system and comparing the results of Weighted OFDM scheme, predicted scheme and with conventional OFDM system.
