Abstract
Techniques for modulation and demodulation using near-Nyquist sampling operate using substantially band-limited signal. In modulating, the substantially band-limited signal is formed by filtering modulated symbol date to produce a complex sample stream having a bandwidth of less than the twice the associated symbol transmission rate and with a sample rate of less than twice the symbol rate. In demodulating, a substantially band-limited signal having a bandwidth of less than twice the associated symbol transmission rate is sampled at a sample rate of less than twice the symbol rate of the modulation.
