Pulse superposition: a technique for peak-to-average power ratio reduction in OFDM modulation

A new technique for the control of the peak power in OFDM modulation, called pulse superposition, is presented. The proposed technique adds to the original OFDM signal a peak-reducing signal composed of Gaussian impulses centered on the peaks of the OFDM signal in the time domain. The technique combines effectiveness and low complexity, requires only a modest amount of side information and does not lead to signal-to-noise ratio reduction. In this paper, simulation results are presented.
