Abstract :
Orthogonal frequency division multiplexing (OFDM) is the most popular modulation technique in modern wireless communication systems involving high data rates. However, due to the large number of sub carriers used, OFDM systems have a large dynamic signal range with a very high peak-to-average-power ratio (PAPR) which makes OFDM sensitive to nonlinear effects. In this paper, a comparative study of PAPR reduction performance is studied using various channel coding techniques for the OFDM signals. Here, for performance analysis Hamming codes, Cyclic codes are considered. It is shown that each of the channel coding techniques has a different PAPR reduction performance and the coding technique with better PAPR performance is identified.
