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 we can reduce PAR, but practical implementation is complex, to overcome this we use l1 minimization in addition to FITRA algorithm which can reduce computational complexity of FITRA. We compare our results with FITRA.We prove that our method will reduce computational complexity of FITRA.
