Improving Error Probability Performance of Digital Communication Systems with Compact Nyquist Pulses

摘要

Designing pulse shaping filters that satisfy the Nyquist condition for minimum intersymbol interference (ISI) is crucial to the performance of almost all digital transceiver systems. In this paper, a method of improving the error probability performance of various Nyquist pulses, by multiplying them with a specific compactly supported function, is proposed. The resultant pulses are less sensitive to timing error and with smaller maximum distortion than the original pulses. Tabulated results that compare the error probability performance of the improved pulse technique to some conventional pulses are provided.
