DIGITAL PULSE INTERVAL AND WIDTH MODULATION

This article investigates the implementation of a new digital pulse-ti me modulation (PTM) technique based on a digital pulse interval and wi dth modulation (DPIWM) scheme. Original expressions are presented for code characterization, channel capacity, and power spectral density. T hese illustrate the advantages of this scheme compared with convention al pulse-code modulation (PCM). Both theoretical and simulated spectra l results are given, and are shown to be in close agreement. (C) John Wiley & Sons, Inc.
