A Parallel Demodulation Method for High-rate QPSK Signal
In order to implement high-speed data demodulation, parallel demodulation model for QPSK signals is proposed, and the parts of the model including tuning synchronization, carrier synchronization, automantic gain control (AGC ) and data recovery are simulated. Especially, a method for phase ambiguity unifying and data recovery after carrier synchronization in parallel demodulation is put forward and simulated.
