Paper Abstract

Atmospheric scintillation negatively affects point-to-point laser communication requiring either an increase in power to maintain link throughput rate or decreasing the data rate at a constant power. The effect of atmospheric scintillation on irradiance can be modeled using a gamma-gamma probability distribution. With the model of irradiance known, the Poisson transform of the irradiance is determined. Using the Poisson transform of the gamma-gamma distribution, the probability of word error is calculated for a pulse-position modulation (PPM) receiver. The word error probability for M-ary PPM decoding is then plotted with respect to varying turbulence parameters.
