Next generation wireless communication networks (NGN) uses one of the emerging multicarrier multiplexing transmission techniques which is known as orthogonal frequency division multiplexing (OFDM). It provides several advantages such as offering greater immunity to multipath fading & impulse noise, eliminating inter-symbol interference (ISI), inter-carrier interference (ICI) & the need for equalizers. However, OFDM have a generic problem of high peak to average power ratio (PAPR) which is defined as the ratio of the peak power to the average power of the OFDM signal. In this paper, an improved design of amplitude clipping & filtering method is proposed and implemented which shows the significant improvement in case of PAPR reduction compare to an existing method.
