The encoded data, which is in orthogonal space, modulates the carrier frequency by means of On-Off Keying. At the receive side, the data is recovered by means of code correlation. This modulation technique offers channel coding and modulation, and synchronization without any additional circuits. These techniques are especially beneficial in high bandwidth and secure laser communication applications, such as for use in Unmanned Aerial Vehicles.
