In the current literature on free space optical (FSO) communication, typically open-loop designs are considered where the knowledge of channel state information is only available at the receiver. This is mostly favorable in the context of time-varying channels where the feedback implementation becomes problematic. Atmospheric turbulence channels in FSO systems exhibit quasi-static nature. The feedback information can be reliably transmitted, therefore makes possible the use of channel state information at the transmitter side. Such close-loop systems where transmission parameters are adaptively adjusted according to the channel conditions are widely used in radio frequency wireless communications. In this work, we consider adaptive transmission techniques in the context of FSO systems with multiple apertures and investigate their performance.
