Modeling The Atmosphere As An Unguided Optical Communications Channel
SPIE Proceedings, 1989Due to the increasing number of applications for optical communications, methods such as computer simulation are needed for the performance analysis of these systems. The objective of this paper is to propose a system level model for simulating the Earth's atmosphere as an unguided optical communications channel.

The model of an atmospheric communication channel with phase noise
2010 20th International Crimean Conference "Microwave & Telecommunication Technology", 2010The model of the communication channel with phase noises is proposed. The prototype of synchronization system, which works at the phase noises in the communication channel, is made. The research of the pseudorandom signal spectrum is carried out depending on the shift register size in the m-sequence generator.

The atmospheric semidiurnal lunar tide is added to the Whole Atmosphere Community Climate Model (WACCM) through inclusion of an additional forcing mechanism. The simulated climatology of the semidiurnal lunar tide in surface pressure and zonal and meridional winds in the mesosphere and lower thermosphere (MLT) is presented.

Journal of Climate, 2008
Abstract Transport of momentum by convection is an important process affecting global circulation. Owing to the lack of global observations, the quantification of the impact of this process on the tropospheric climate is difficult. Here an implementation of two convective momentum transport parameterizations, presented by Schneider and ...

Atmosphere Propagation and Communication Channel Model for Laser Wavelengths
IEEE Transactions on Communications, 1970The advent of the laser has generated much interest in its use for communication. Consideration is given in this paper to obtaining a communication channel model of the atmosphere for laser frequencies. For this purpose a fairly exhaustive, tutorial, and partly critical review of a major part of the extensive literature pertaining to theoretical and ...
