Orthogonal frequency division multiplexing (OFDM) undergoes a problem known as peak to average power ratio (PAPR).Selected mapping (SLM) and clipping are the efficient techniques to diminish the PAPR. Hence, in this paper, a frequency domain cyclic shift sequence (FDCSS) based scheme combined with SLM and clipping technique is proposed for the reduction of PAPR. Careful selection of the shifting values, clipping level, and phase sequence reduces PAPR and improves the performance OFDM system. The results of this novel scheme are validated through Matlab simulations under various phase sequences, sub-carriers and shifting values.
