Abstract

We propose an FSO receiver with adaptive-gain stage and associated filtering to reduce signal amplitude excursion and noise for decoding the received symbols with low error rate. A digital synchronization method together with a sampling strategy is developed for a FPGA-based receiver. The proposed techniques are evaluated through simulation and laboratory experiments under real turbulence.
