Abstract
An apparatus for detecting group delay information over frequency for a transmission medium has: a receiver for receiving a measurement signal, the measurement signal comprising at least a first carrier signal at a first carrier frequency, a second carrier signal at a second carrier frequency and a third carrier signal at a third carrier frequency; a frequency analyzer for analyzing the reception signal to obtain reception phase information on the first carrier signal, the second carrier signal and the third carrier signal; and a processor for forming a first combined piece of phase information and for forming a second combined piece of phase information, for forming a first piece of group delay information and for forming a second piece of group delay information, and for associating the first piece of group delay information to a first frequency and the second piece of group delay information to a second frequency.
