    reduction of papr in ofdm system

    Papr should be reduced to increase amplifiers efficiency. The lower papr, the better amplification you will get in the RF stage. Using precoded matrix is a good option if you have computational power enough. Propoer papr reduction is not distorting your signal, and hence, no SNR degradation or...
