Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is one of the most promising technique for today’s wireless broadband communication systems.3GPP’s LTE was the first to adopt OFDM as its downlink technique. One of the major disadvantage is its high peak to average power ratio (PAPR). In this paper various PAPR Reduction Techniques are discussed along with their advantages, disadvantages and improvements done so far. Techniques like clipping, Commanding, Selective Mapping (SLM), Interleaving, Tone Reservation (TR), Tone Injection (TI), Partial Transmit Sequence (PTS), etc.
