Abstract

A novel scheme that employing the coherent receiver in atmospheric laser communication system was proposed in this paper. DPSK format modulation is adopted to overcome atmospheric turbulence and multipath fading. Coherent receiver is used to improve system´s sensitivity. Testing bed was setup and eye diagram can be measured. Real time BER would be measured soon.
