Phase spectrum of a 16- PSK modulated signal

praveenmv
I am working on open loop modulation techniques which require me to analyze the phase spectrum of a signal. Are there any techniques by which I can measure the phase spectrum of the modulated signal with respect to a reference signal.(Average frequency of the modulated signal is known)

  • I am realizing phase modulation by selecting a series of delayed signals of same frequency appropriately through a multiplexer. The multiplexer is controlled by a delta sigma modulator. I am interested in viewing the phase spectrum of the modulated signal. As of now I am using an ideal PFD (by knowing the reference signal and its frequency)  and getting the phase spectrum from its output. But I found that there are some shortcomings in this method. Is there a easier method by which I could get the phase information?
