Compensate the phase rotation of the RF. WARNING: This function is currently unused. It has not been tested!
@param pilot_type indicates whether it is a CHBCH (=0) or a SCH (=1) pilot
@param initial_pilot index of the first pilot (which serves as reference)
@param last_pilot index of the last pilot in the range of pilots to correct the phase
@param ignore_prefix set to 1 if cyclic prefix has not been removed (by the hardware)
