Book excerpt: In the last couple of years, wireless communications have experienced a quick growth due to the ubiquitous mobility, super internet speed and huge multimedia services & applications. Orthogonal frequency division multiplexing (OFDM) is an emerging research field of wireless communication and finds its application where high data rate is required at low latency and better spectral efficiency. OFDM signals 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. The drawback of high PAPR is that the dynamic range of the power amplifier (PA) and digital-to-analog converter (DAC) during the transmission and reception of the signal is higher. The main focus of this research is to design & implement a new PAPR reduction scheme based on amplitude clipping & filtering method which reduces the PAPR significantly. Simulation results show the considerable improvement in case of PAPR reduction compare to an existing method. Besides these, overview, motivation & different types of analysis of PAPR reduction techniques are discussed in this book.
