Wireless optics

    1. The problem statement, all variables and given/known data

    Well, I´m doing a project about FSO (Free Space Optics), it deal with optical communication but without fiber, only by air. Then, I have already studied the transmitter (gaussian source), the channel and I know I need a photodetector APD for the receiver but my questions is: how can I study how much power there is on the receiver?
    I also know power on the receiver is the difference between power on the transmitter and loss on the way. Nevertheless in the receiver a bit of power is lost because of the aceptation cone.
    So how can I calculate this energy loss??

    Thank you for help me.
