Is OFDM an Optimal Multi-Carrier Modulation System in Terms of PAPR Performance?
Résumé
Several Multi-Carrier Modulation systems based on different waveforms and pulse shapes are competing nowadays the conventional Orthogonal Frequency Division Multiplexing (OFDM) system based on the Fourier transform and the rectangular filter, in terms of Bit Error Rate, Spectral Efficiency, computational complexity, and other measures. In this paper, we prove analytically that, under certain constraints on the modulation scheme, conventional OFDM has an optimal Peak-to-Average Power Ratio performance.
