Paper Abstract
Orthogonal On-Off Keying is a coded modulation technique, where the input digital signal is mapped into a block of
orthogonal codes. The encoded data, which is in orthogonal space, modulates the laser beam by means of On-Off
Keying. At the receiver, two photo cells are Cross Coupled to compensate the sunlight and other atmospheric noise.
Since the laser beam is highly directional and can only be acquired by one photo cell, the input laser signal can then be
received with little noise, and signal processing is made easier. These techniques are especially beneficial in high
bandwidth, long distance secure laser communication applications, such as for use in Unmanned Aerial Vehicles.
