Design of Nyquist and near-Nyquist pulses with spectral constraints
Two design procedures, one based on switched pulse shapes, and the other based on alternating projections in the time and frequency domain, are used to obtain interference and jitter-free or reduced interference and jitter (near-Nyquist) pulse-shaping filters. The latter method, that incorporates both frequency- and time- domain constraints into the linear filter design procedure, allows common pulse-shaping filters to be used for both QPSK and 8-PSK used in contemporary satellite modems.
