Abstract

Cognitive radio technology allows unlicensed user to utilize the free licensed band intelligently to solve the problem of scarcity in the spectrum with the increase in use of wireless communication. Cognitive radio has the capability to learn and adapt their wireless transmission according to the surrounding radio environment. Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation technique which is used in cognitive radio because of its capability of overcoming the problem of low data rate transmission. OFDM is high data rate transmission technique. The main issue of OFDM is high PAPR (peak to average power ratio). Various techniques such as clipping, coding, selective mapping (SLM), partial transmit sequence (PTS) and tone reservation, are available to reduce the PAPR. In this paper, a new approach of hybrid technique (combination of PTS and clipping technique) is proposed.

Keywords- Cognitive Radio, OFDM, PAPR, PTS, Clipping
