Real-Time Verification of Transmitter-Side Frequency Shift for Doppler-Shift Compensation in Free Space Optical Coherent Communication
It was demonstrated that a digital coherent signal processing circuit with a transmitter-side frequency shift function can compensate for 2 GHz Doppler-shift, and that the nonlinearity of the output amplitude of DAC.
