Differential Multi-Pulse Position Modulation for Free Space Optical Communication
In order to improve the laser output power in free space optical communication, it is necessary to improve the power efficiency of laser modulation as much as possible, in the case of the limitation of the laser. In this paper, based on the theory of pulse position modulation (PPM), a differential multi-pulse position modulation(DMPPM) scheme was designed, by consulting the structure characteri...
متن کاملOutage Analysis in MIMO Free-Space Optical Channels with Pulse-Position Modulation
Free space optical communication is an attractive alternative to radio frequency for the purpose of transmitting data on the order of gigabits per second. The main drawback in communicating via the free space optical channel is the detrimental effect the atmosphere has on a propagating laser beam. Atmospheric turbulence causes random fluctuations in the irradiance of the received optical laser ...
متن کاملImproved Markov Models for Terrestrial Free-Space Optical Links
Finite-state Markov chains are a useful tool for modelling communication channels with correlated fading and have recently also been applied with success to terrestrial free-space optical (FSO) communication channels. However, the issue of how such Markov models should be optimized in order to accurately approximate the original continuous fading channel has not been addressed in a systematic m...
متن کاملDiscrete-Time Demodulator Architectures for Free-Space Broadband Optical Pulse-Position Modulation
The objective of this work is to develop discrete-time demodulator architectures for broadband optical pulse-position modulation (PPM) that are capable of processing Nyquist or near-Nyquist data rates. These architectures are motivated by the numerous advantages of realizing communications demodulators in digital very large scale integrated (VLSI) circuits. The architectures are developed withi...
متن کاملPacket testing in free-space optical communication links over water
NRL’s Chesapeake Bay lasercom test facility (LCTF) offers a variety of ranges for researching free-space optical laser communication (FSO lasercom) links in a maritime environment. This paper discusses link performance over the 16 km one-way range at the LCTF. There are several methods to determine the link quality in FSO lasercom. Bit-error-rate (BER) testing and packet testing are two possibl...
