摘要
Abstract
This paper proposes a PSK external modulation-based laser communication system.Using a 637 nm all-solid-state la-ser as a light source and FPGA demoboard as the modem hardware to control the acousto-optic modulator,this system applies the modulated signals to the laser and,using a photomultiplier tube as a laser receiver via atmospheric channel transmission, improves the traditional PSK demodulation,eliminates phase ambiguity and sets up a complete experiment platform for laser communication systems,realizing a laser communication system with the serial communication rate of 1 1 5.2 kbit/s and bit er-ror rate of lower than 10 -8 .关键词
