Abstract :
In existing digital telecommunication systems, where modulation on a carrier frequency is used, coherent demodulation is often applied. In the case of suppressed carrier systems, nonlinear signal processing in the loop phase detector is unavoidable. A comparison of three different phase detectors was carried out for QPSK modulation. The analysis was conducted using computer simulation
