—Mobile communications has become one of the most developed technologies in the last two decades. Strong demand to increase system capacity is still growing dramatically and non-orthogonal transmission schemes are being considered as a potential solution to improve spectral-power efficiency. The non-orthogonal transmission scheme called Faster-Than-Nyquist(More)
—Capacity computations are presented for Faster-Than-Nyquist (FTN) signaling in the presence of interference from neighboring frequency bands. It is shown that Shannon's sinc pulses maximize the spectral efficiency for a multi-access channel, where spectral efficiency is defined as the sum rate in bits per second per Hertz. Comparisons using root raised(More)
