Abstract
We investigate faster-than-Nyquist modulation based on short finite
pulses over the AWGN channel. We consider several pulse
shapes and compare their information rates for several system setups. We compare the effect of increasing the alphabet size versus of increasing the signaling rate. The outcome is that for these pulses the FTN symbol rate
is of greater importance than the alphabet size. Finally we test some
concatenated coding schemes where faster-than-Nyquist modulation
constitutes the innermost encoder; the outcome is very good.
