Analysis of Sensitivity of Photoconductive Receivers for Free space optical communication systems

چکیده
In this paper we examine theoretically the performance of an optical receiver based on an Hg0.77Cd0.23Te photoconductive detector for its possible application at 9.6 μm free space optical communication system at moderate bit rates. A rigorous noise model of the receiver has been developed for this purpose by incorporating all significant sources of noise. Our analysis reveals that the photoconductive receiver exhibits sensitivity of -50 dBm at a bit rate of 100 Mb/s and -45 dBm at a bit rate of 1Gb/s and total mean-square noise current

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...

متن کاملSensitivity modeling of binary optical receivers.
The sensitivity characteristics of optical receiver frontends for high-speed data communications depend on modulation format, detector type, and specific operational constraints. A general mathematical model of the receiver sensitivity that fits to analytical as well as measured data is required to compare different receiver implementations and assess the reliability of data links under varying...
متن کاملPerformance Analysis of Communication Systems over Mimo Free Space Optical Channels
The global telecommunications network has seen massive expansion over the last few years. Optical communication through clear atmosphere provides a means for high data rate communication over relatively short distances (e.g. 2km). However, the turbulence in the atmosphere leads to fades of varying depths, some of which may lead to heavy loss of data. Free space optical communication system usin...
متن کاملEfficiency of complex modulation methods in coherent free-space optical links.
We study the performance of various binary and nonbinary modulation methods applied to coherent laser communication through the turbulent atmosphere. We compare the spectral efficiencies and SNR efficiencies of complex modulations, and consider options for atmospheric compensation, including phase correction and diversity combining techniques. Our analysis shows that high communication rates re...
