We extend Mazo's concept of faster-than-Nyquist (FTN) signaling to pulse
trains that modulate a bank of subcarriers, a method called two dimensional
FTN signaling. The signal processing is similar to orthogonal frequency
division multiplex (OFDM) transmission but the subchannels are
not orthogonal. Despite nonorthogonal pulses and subcarriers, the method
achieves the isolated-pulse error performance; it does so in as little as half the bandwidth of ordinary OFDM. Euclidean distance properties are
investigated for schemes based on several basic pulses. The best have Gaussian shape. An efficient distance calculation is given. Concatenations of ordinary codes and FTN are introduced. The combination achieves the
outer code gain in as little as half the bandwidth. Receivers must
work in two dimensions, and several iterative designs
are proposed for FTN with outer convolutional coding.
