In this paper; OFDM based on Software-Defined Radio (GNU Radio) to reducing the peak to average power ratio is developed and tested. Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital communication; whether wireless or over copper wires; used in applications such as digital television and audio broadcasting; DSL Internet access wireless networks and 4G mobile communications. In this proposed design a weight is imposed on each discrete OFDM signal via a certain kind of a band limited signal; and an OFDM signal formed with the weighted discrete data is then considered before a high power amplifier (HPA); whereas the original signal can be recovered completely at the receiver side using weighted OFDM scheme & we doing it using to be implementing on Blade RFx40 SDR platform and the performance is going to be analyzed. BladeRFx40 is a Software Defined Radio (SDR) platform designed to enable a community of hobbyists and professionals to explore and experiment with the multidisciplinary facets of RF communication.
