Digital pulse interval and width modulation

This article investigates the implementation of a new digital pulse-time modulation (PTM) technique based on a digital pulse internal and width modulation (DPIWM) scheme. Original expressions are presented for code characterization, channel capacity, and power spectral density. These illustrate the advantages of this scheme compared with conventional pulse-code modulation (PCM). Both theoretical and simulated spectral results are given, and are shown to be in close agreement.
