Cyclostationary analysis - Find baudrate

Hi All,

I am trying to do perform cyclostationary analysis to determine the
periodicity of the signal to find the symbol or baud rate of the raw
modulated data. I am trying to use GRC setup described in gr-baz. (
File:GRC Variable Delay Cyclo.png - SpenchWiki). Can
someone help me to explain how I should modify the variable delay to
achieve this.

Thank you
