Anti-Disturbance Techniques for Laser Transmitting Command Systems

Aim To investigate techniques heightening the performance of anti disturbance for a Laser Transmitting Command Systems (LTCS). Methods Soft decision was used to achieve synchronization acquisition; (24,12) extended Golay code was selected and a method of decoding with soft decision was used; an experimental device, that could imitate the disturbance behavior of laser transmitting channel and the procedure transmitting command, was designed. Results Average probability of bit error was little comparatively. Conclusion The technique scheme described can enhance the anti disturbance performance of the LTCS.
