OFDM is a transmission scheme that offers diversity in frequency selective fading environments but suffers from high PAPR. Many researchers have studied the appropriate coding scheme to reduce PAPR and offer good error control properties as well. This paper reviews the major results obtained up to date for the reduction of PAPR. Various scrambling techniques like PTS and SLM have been combined with clipping-filtering and DCT to reduce PAPR. The various coding techniques like Block Coding and Reed Muller codes have been evaluated in this paper to obtain significant reduction in PAPR. CCDF graphs depict performance of proposed techniques.
