The systems which have the high peak-to-average power ratio that is OFDM systems which degrades the performance of the amplifier. To overcome this, various distortion and distortion less algorithms are suggested. The Partial Transmit Sequence (PTS) is the technique that is distortion less which separates the sequences of input to the subsequences and selects minimize optimized PAPR in the signal to the transmission. To minimize the PAPR, further energy compaction of signal and minimum
