A NOVEL BLIND TRACKING METHOD FOR HIGH-SPEED LASER COMMUNICATION

In this paper, a novel decision feedback tracking method is proposed, which is based on frame demodulation for high-speed laser communication with less prior information. In order to reduce the length of the pilots and improve the tracking accuracy, a frequency control word addressing and pointing decision algorithm are introduced to recover the local pseudo code from the received data for tracking. Simulation results demonstrate that in the high-speed laser radar communication, this method has better tracking performance than traditional methods when the pilot length is short.
