Abstract

In optical wireless communications, a channel-matched adaptive coherent receiver may be implemented using an array of receive apertures. After atmospheric channel fading estimation, several replicas of a message received through the atmosphere are combined. As an alternative to training-based channel estimation, we analyze the performance of sequential techniques for direct optimization of multi-aperture array receivers in free-space coherent laser communications.
