A new selected mapping scheme without additional IFFT operations in OFDM systems

Examine the impact of Modulation Order and Sub-bands on PAPR Reduction Techniques using Various Modulator in 802. 11a/b/g

“…These schemes can be further classified into two prominent types which are signal distortion and signal scrambling techniques. One of the common schemes include in Signal scrambling techniques are Selected mapping (SLM) scheme" [5], [6], [8]" and Partial transmit sequence (PTS) schemes" [3], [4], [7], [10,[12]". Among all these schemes, the SLM and PTS schemes have been considered the most efficiently schemes due to its high PAPR reduction performance without incurring additional signal distortion.…”
