After more than thirty years of research and growth carried out in the field of communication OFDM has been widely implemented in high speed digital communication. In this paper, PAPR is reduced at downlink scheme by using PMP pre coding at transmitter section. By using FITRA algorithm with l infinity minimization the authors can reduce PAR, but practical implementation is complex. To reduce computational complexity of FITRA with hardware implementation they apply minimization to FITRA algorithm with respect to compressed sensing. They prove that this algorithm will reduce PAR efficiently with increased SNR.
