The Design of a Pulse-Position Modulated Optical Communication System
In recent literature the advantages of an idealized narrow-width pulse-position modulated (PPM) optical communication system, using coherent sources and direct photodetection, have been shown. In this
An improvement of optical PPM communication with high security
Thus, this paper presents an optical scheme on modulation and receiver that eliminate those drawbacks. The technologies that have had the social impact on communications technology in the 20th century
An improvement of optical PPM communication with high security
To further clarify this advantage, a theoretical concept has been proposed to solve the problem by adopting a PPM code format. However, this scheme has several difficulties at the
GMW Associates
Point-to-Point links are available in stand alone and modular rack versions and can be supplied with EMI shielding for operation in harsh electrical environments.
Pulse Position Modulation (PPM) and Variants
This allows for even greater data density compared to standard PPM or DPPM alone, as both pulse position difference and amplitude are used to represent different symbols. The receiver must

PPM Systems specialises in: RF over fibre systems (SIGINT and COMINT), antennas and stacked antenna systems, software-defined radio, RF filtering and conditioning, EM spectrum and decoding
Design of Optical Pulse Position Modulation (PPM) Translating Receiver
M-ary pulse position modulation (M-ary PPM) signaling is a means of transmitting multiple bits per symbol in an intensity modulated/direct detection (IM/DD) system. PPM is used in
Optical Receiver for PPM: Which system is best suited?
My task is to build a wired optical communication system with a bit rate of at least 100 MBit/s, better would be 1 GBit/s. As Modulation scheme PPM (Pulse Position Modulation) is used. For first tests
Design and Analysis of a First-Generation Optical Pulse-Position
In this article, the requirements and design of a prototype pulse-position mod-ulation (PPM) receiver are considered.
Nested PPM for Visible Light Communication With Heterogeneous
We address the question, whether it is viable to support both heterogeneous receiver types simultaneously, using a single LED-based transmitter, and characterize the trade-offs associated
PPM demodulation: On approaching fundamental limits of optical
We present a general framework of optical receivers known as the conditional pulse nulling receiver, and present new results on ultimate limits and achievable regions of spectral versus
