Abstract

Orthogonal frequency division multiplexing (OFDM) is a type of multicarrier modulation technique in which entire bandwidth is divided into large number of small sub-carriers and each subcarrier is transmitted parallel to achieve higher data rates. It is used in various applications like Digital audio broadcasting (DAB), Digital video broadcasting (DVB) & wireless LAN. OFDM is a attractive modulation scheme with strongly efficient in bandwidth usage, immunity against multipath fading environment. It has less ICI and ISI and provides better spectral efficiency. Although it has various advantages but still certain disadvantages are: high Peak to average Power ratio, high bit error ratio (BER) & synchronization problem. This paper will focus on various PAPR reduction techniques and conclude with comparison between various techniques.
