In this scheme, the preset peak reduction tone (PRT) set would be divided int based tone reservation (IRLS-TR) method that offers high PAPR reductions in OFDM systems is proposed. The method generates the required peak-reducing signal by utilizing a robust iterative re-weighted least-squares algorithm for minimization of the infinity norm to approximate the desired peak-reducing signal. This IRLS- the PAPR in OFDM system is the tone reservation method (TR). In our work we propose a modified tone reservation method to decrease the PAPR with the high and low amplitudes at the same time. An image of size 128×128 is used as a source of data that transmitted using OFDM system.

Abstract —As an adaptive method to combat doubly selective channel, chirp-based orthogonal frequency-division multiplexing (Chirped- OFDM) also suffers from a high peak-to average power ratio (PAPR).
