Phase Shift Measurement and Phase Equalizer

    I am attempting to characterise a phase shift in a channel so that I
    can compensate it at the receiver end using a phase equalizer. I need a
    method which produces a phase shift curve with more measurements than a
    Lissajous method produces. I was thinking possibly a phase shift
    oscillator may be the way to go with each stage producing a 45 degree
    shift, but I am unsure how to use this. I want to define the frequency
    and calculate the resulting shift. Also, I am not sure how to use an
    equalizing filter. I would probably use an all pass filter but how can
    I define where the curve goes?

    Please help. I am mightily perplexed!!!
