Abstract :
This paper explores the potential benefit of recently proposed spectrally-efficient frequency-division multiplexing systems (SEFDM), when compared to traditional orthogonal frequency-division multiplexing (OFDM) systems. First, the considered SEFDM channel model is described, then we obtain an expression for the capacity of this channel in case of un-precoded transmission. We evaluate the channel capacity for various practical continuous-time modulation pulses. Numerical capacity results indicate that SEFDM can lead to channel capacity improvement over OFDM for some considered pulses, especially at relatively high SNR´s.
