Par Reduction In Mu-Mimo-OFDM Based On Fitra In Applicable To Compressed Sensing
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 reduce
computational complexity of FITRA with hardware implementation we apply l1 minimization to FITRA algorithm with
respect to compressed sensing. We prove that this algorithm will reduce PAR efficiently with increased SNR.
