In recent years, there is a rapid growth in multimedia based applications which require technology which support high data rate transmission. Orthogonal frequency division multiplexing (OFDM) is the efficient multiplexing and modulation technique adapted for 4G wireless communication applications. OFDM is high speed data transmission scheme in wireless communication. The one of the main disadvantage of the OFDM is peak to average power ratio PAPR. Mainly, because of non linearity of high power amplifier, these results intercarrier interference and degradation of bit error rate (BER). OFDM consist of large number of independent sub carriers as a result of which amplitude of such signal have high values. However, as the number of sub carrier’s increase PAPR also increases. The different PAPR reduction techniques are available, such as Clipping, Compading, Selective Mapping (SLM), Tone Injection (TI), Tone Rejection (TR) and Partial Transmit Sequence (PTS). In this paper, a new approach is proposed in which hybrid techniques are used partial transmit sequence (PTS), filtering and compading.
