Next generation wireless communication system uses one of the most competent multi-carrier transmission techniques known as Orthogonal Frequency Division Multiplexing (OFDM). OFDM has several characteristics such as providing greater immunity to multipath fading & impulse noise, eliminating Inter Symbol Interference (ISI) & Inter Carrier Interference (ICI) using a guard interval known as Cyclic Prefix (CP). But, OFDM suffers a serious drawback of high peak to average power ratio (PAPR) which is defined as the ratio of the peak power to the average power of OFDM Signal. A lot of researches are carrying on reducing this high PAPR. In this paper, we investigated the performances of different higher order modulations on our previously designed amplitude clipping & filtering method to reduce PAPR.
