Abstract
Orthogonal Frequency Division Multiplexing (OFDM) is a special case of multicarrier transmitted, where a single data stream is transmitted over a number of lower rate subcarrier. One of the main issues of OFDM is high Peak-to-Average Power Ratio (PAPR) of the transmitted signal which adversely affects the complexity of power amplifiers, In this paper we will discuss techniques used to reduce PAPR selective mapping (SLM), clipping, partial transmit sequence (PTS), techniques are implemented for PAPR reduction of OFDM signal at transmitter. Comparison of these PAPR reduction techniques is done based on CCDF and BER performance of the system.
