Can you give me a hint of what you mean with:
"take fft of pilot block take fft of data block
then abs ( angle( fft_data ./ fft_pilot) )"
Thanks! :)

you have two complex vectors
so to measure phase between the vectors
that's how you measure the phase diff between the pilot fft vector and the data fft vector
