Luminescent detector for free-space optical communication

Incremental adaptive networks implemented by free space optical (FSO) communication

The aim of this paper is to fully analyze the effects of free space optical (FSO) communication links on the estimation performance of the adaptive incremental networks. The FSO links in this paper are described with two turbulence models namely the Log-normal and Gamma-Gamma distributions. In order to investigate the impact of these models we produced the link coefficients using these distribu...

Free Space Optical Communication for Tactical Operations

Cooperative Communication in Free Space Optical Systems

We have investigated the performance improvement of cooperative free space optical (FSO) communication over single input single output (SISO) system in this paper. Bit error rate (BER) analysis for gammagamma channel model with additive white Gaussian noise (AWGN) has been demonstrated for SISO and cooperative system as well where the performance improvement with different combining techniques ...

Mobile Free Space Optical Communication System

The paper discusses a low power consumption, light weight and low cost 10MHz free-space optical communication (FSO). The system is designed for mounting on mobile platforms, with effective range of at least 50 meters. LightEmitting Diodes (LEDs) and Laser diodes (LDs) are used in the transmitter for comparison for their relative performance in the system. The receiver features a beam splitter t...

Terrestrial Coherent Free-Space Optical Communication Systems

In the past three decades, the demand for high-speed communications has increased dramatically, while fiber optical communications has been applied in the majority of data transmission networks. Optical fiber has advantages over existing copper wire in long distance and high demand applications. The ever increasing need for higher bandwidth and higher speed optical data and communications trans...
