Orthogonal Frequency Division Multiplexing (OFDM) has been currently under intense research for broadband wireless transmission due to its robustness against ulti-path fading. In multicarrier modulation, the most commonly used technique is OFDM, it has recently become very popular in wireless communication. The main drawback of OFDM is Peak to average power ratio (PAPR). This paper present selective mapping (SLM) technique and partial transmit sequence (PTS) technique to reduce PAPR. These proposed techniques show better performance to reduce PAPR.
