The Orthogonal frequency division multiplexing (OFDM) is the most commonly used digital communication technique for transmitting large data over radio waves. Although OFDM is the most commonly efficient method of transmission, a drawback emerges from the mode of transmission which is the PAPR (peak to average power ratio). The peak to average power ratio goes high when the partially transmitted waves of OFDM are added up. These peaks cause many issues which are discussed here in this paper. This paper also gives a detailed outline of OFDM. The method to overcome the PAPR effect is also discussed.
