Atmospheric Turbulence and Pointing Errors Effects in the Performance Matrices of Wireless Optical Links
Journal Title: International Journal of Electronics Communication and Computer Technology - Year 2015, Vol 5, Issue 2
Abstract
The average channel capacity and bit error rate parameters of free space optical link under atmospheric turbulence modelled by Gamma-Gamma distribution and Kdistribution respectively with pointing error effects has been analysed. The performance indices have been plotted against transmitted power and compared. It has been observed that channel capacity has a slight improvement during night time due to less turbulence effects due to reduced temperature fluctuations in the atmosphere.

A Lossless Secret Image Sharing Scheme based on Pixel Partitioning
Secret sharing method divides a secret into some components called shadow images where each shadow image looks meaningless. Based on this idea, we propose a simple secret image sharing scheme in this article. This schem...
A 1.8V and 2GHz Inductively Degenerated CMOS Low Noise Amplifier
This paper presents the design and simulation of Low Noise Amplifier (LNA) in a 0.18?m CMOS technology. The LNA function is to amplify extremely low noise amplifier without adding noise and preserving required signal to...
Reversible Multiplier with Peres Gate and Full Adder
Low Power dissipation and smaller area are one of the important factors while designing multipliers for digital circuits. As multipliers used in digital circuits dissipate large amount of heat whenever there is a tran...
