Abstract

We address the problem of classification of binary phase-shift keying-modulated multicarrier signals with the peak-to-average power ratio (PAPR) exceeding 3/4 of the maximal possible value. By providing a simple characterization of such signals, we derive an upper bound on their number, and propose a simple sufficient condition for the signals to have low PAPR. Based on this, we describe a simple method for generation of signals with guaranteed PAPR gain of more than 2.5 dB using only two redundant tones.
