Abstract
Merged selected mapping (SLM) scheme is presented for reducing peak-to-average power ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM). The concept of the proposed SLM scheme is based on a combination of advantages of the conventional low complexity SLM schemes by dividing inverse fast Fourier transform (IFFT) into k stage and remaining n-k stage and, then generating additional OFDM signal sequences without performing IFFT to the conventional SLM scheme. This scheme dramatically reduces computational complexity comparing with the conventional SLM schemes under the similar PAPR reduction performance.
