Abstract

Orthogonal Frequency-Division Multiplexing (OFDM) is considered to be a most viable option to convey information at high data rates in wireless communication. OFDM is multi-carrier communication technique which uses orthogonal subcarriers and has high bandwidth spectral efficiency and robustness to high-frequency selective fading channels. In spite of several advantages, OFDM has the major drawback of Peak-to-Average Power Ratio (PAPR), which may lead to power inefficiency in RF transmission section, high in-band, and out-of-band radiation, inter-carrier interference, and degradation in Bit Error Rate (BER) performance. Hence, it is extremely preferred to have minimum PAPR. This paper proposes a novel technique of reducing peak-to-average power, improving the bit error rate performance, and saving bandwidth by the combination of novel PAPR reduction technique and adaptive DPD. The proposed method gives a better PAPR reduction as well as better BER performance compared to other methods.
