Hi,
Coherent demodulation can be used for QPSK demodulation.To obtain demodulated output from I channel, multiply the incoming QPSK signal with cos2Πfct and use LPF ., and to obtain the demodulated output from Q channel,multiply the incoming QPSK signal with sin2Πfct and use LPF.
The outputs from I and Q channels would be the demodulated symbol consisting of two bits.
Hope u got my answer.
Regards
Bhanumurthy.
