Paper Abstract

The model of laser communication system using in vehicle mobile target was built. Optimal design and calculation was analyzed for system performance, such as laser transmission, photoelectric reception and speech information processing and image stabilization. Algorithm of MELP (Mixed Excitation Line Predication) compressed speech scrambling was received in processing voice message, which reached 2.4 kbps digital speech code stream, and realized digitization of laser communication. It was also analyzed carefully about the principle theory of MELP algorithm encoding and decoding as well as algorithm realization used in DSP. Image stabilization and tracking were realized by process signal errors which acquired at quadrant error sensors.
