本文提出了星间光通信链路相干零差接收机的面包板模型（BBM）。2.5在初始频偏为± 7 GHz，模拟卫星间距离变化引起的多普勒频移的条件下，以1 e-6的比特率解调出Gbps的BPSK数据，解调灵敏度为-49.1dBm。
This paper presents Bread Board Model (BBM) of coherent homodyne receiver with an optical phase locked loop and a frequency compensator of Doppler shifts for inter satellite optical communication link. 2.5Gbps BPSK data has been demodulated with sensitivity of -49.1dBm at bit rate of 1e-6 under initial frequency offset of +/-7 GHz simulated as Doppler shifts due to variation of distance between each satellite.
