BROWSE_DETAIL_TAB_ABSTRACT

Orthogonal frequency-division multiplexing (OFDM) is a popular wideband multicarrier communication technique and resistive to inter-symbol interference and inter-carrier interference however because of signal’s high Peak to Average Power Ratio (PAPR), efficiency is degraded because of nonlinear distortion. In this study, Tone Injection technique is used with Simulated Annealing optimization algorithm in order to decrease signal’s PAPR with different number of tones and inner threshold is used to decrease necessary number of iterations. Simulation results are compared with other techniques and depict that proposed technique can be used for reducing PAPR of OFDM systems. Designed system is performed on a Software Defined Radio system and using measurements it is shown that nonlinear distortion effect is decreased
