Abstract :
This paper presents considerations regarding the design and implementation of improved Nyquist filters (INFs). Special attention is paid to the use of truncated root-pulse in the practical engineering perspective. A comparison of several INF pulses with hM-1 and hM-3 pulses that suffer no spectral regrowth is made. Although they are outperformed by the hM pulses in terms of spectral regrowth, the pulses generated by INFs are superior in terms of error probability up to one order of magnitude when sampled with a time offset.
