Abstract

Atmospheric noise signals are fundamental limitation of free-space optical communications, as the decrease in signal-to-noise ratio reduces the range and/or bandwidth of the link. In this paper we consider the limitations that this imposes, and investigate the use of discrete wavelet transformation (DWT) to overcome them. Simulations are performed to validate the use of the DWT in the demodulation of the analog data in the presence of noise. Results of the experiments are presented.
