Sammanfattning

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.
