Homodyne BPSK receiver with Doppler shift compensation for inter satellite optical communication
This paper presents Bread Board Model (BBM) of homodyne BPSK (Binary Phase Shift Keying) receiver with an optical phase locked loop and a Doppler shifts compensator for inter satellite optical communication link. 2.5Gbps BPSK data has been demodulated with sensitivity of −49.1dBm at bit error rate of 1e-6 under initial frequency offset of +/−7.5 GHz simulated as Doppler shifts due to relative motion of each satellite.
