Abstract

Communication is a paramount aspect of life and is developing expeditiously. Now days, signals are being sent in digital domain unlike the analog domain which were used previously and single carrier systems are getting swapped by multi carrier systems such as CDMA and OFDM systems. Orthogonal Frequency Division Multiplexing is considered as a propitious technique to counter multipath fading. The shortcomings of an OFDM system is the large value of Peak to Average Power Ratio which is affecting the performance of this system. This paper focuses on scaling down the PAPR by using Peak Reduction Carrier method in Network Simulator (NS-2).
