Capacity of Adaptive Free Space Optical Transmission over Malaga Turbulence with Pointing Error using Truncated Channel Inversion

Abstract

In this paper we consider channel capacity based on Truncated Channel Inversion with Fixed Rate (TIFR) adaptive transmission over Malaga model of atmospheric turbulence with pointing error. Analytical expressions in closed form are derived for capacity based on TIFR adaptive transmission. The impact of cut-off SNR level on channel capacity based on TIFR adaptive transmission is investigated. Also, value of cut-off SNR level for different regimes of transmitter power is considered. Analytical results are numerically evaluated and graphically presented depending on cut-off SNR level and signal to noise ratio (SNR).
