Digital pulse interval modulation for fiber transmission
TLDR
In this paper, a new form of pulse time modulation, termed digital pulse interval modulation (DPIM), is introduced, exhibiting improved performance and relaxed timing constraints compared to digital pulse position modulation.Abstract:
A new form of pulse time modulation, termed digital pulse interval modulation (DPIM) is introduced in this paper, exhibiting improved performance and relaxed timing constraints compared to digital pulse position modulation (DPPM). Theoretical expressions are presented for transmission capacity, code characteristics and power spectral density, along with measurements from a simple experimental prototype, illustrating the advantages of the new scheme.read more

Exact spectral evaluation of the family of digital pulse interval modulated signals
TL;DR: This paper presents a closed-form spectral evaluation of the family of digital pulse interval modulation (DPIM) schemes, where the information is contained in the relative distance between successive pulses.

Stationary model of pulse interval modulation and exact spectral evaluation
TL;DR: A closed-form evaluation of the spectrum of the pulse interval modulated (PIM) signal is given, which takes into account the issue of "stationarization" (in the strict sense) of a PIM signal, which is a necessary task, preliminary to that of spectral analysis.

Error probability of DPPM UWB systems over Nakagami fading channels with receive diversity
TL;DR: Performance results are presented which show that the frame error rate (FER) with DPPM is better than that with PPM, and the FER performance can be improved significantly by receive diversity.

Performance analysis of DPP AM UWB systems over indoor fading channels
TL;DR: Differential pulse position amplitude modulation (DPPAM) is considered in Ultra Wideband (UWB) communic-ation systems and the results show that the FER performance with 2×Nary DPPAM is better than that with 2 ×Nary DPPM and PPM, and MN-ary (M>2) DPPam provides a compromise between FER and complexity.

Analytic and numeric modelling of optical fibre PPM slot and frame spectral properties with application to timing extraction
TL;DR: In this paper, an original numeric model is established and used to predict the spectral properties of optical fiber PPM, which is then used to examine the problems of slot and frame synchronisation in PPM.
