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.
