1. A system, comprising:

  • at least one first sensing device configured for sensing at a first location along a transmission media a first signal propagated over the transmission media in a forward direction and a second signal propagated over the transmission media in a reverse direction opposed from the forward direction, the second signal being a reflected version of the first signal;

    a first signal combiner communicatively coupled to the first sensing device and configured for computing a first sum signal by adding the first and second signals together;

    a first signal subtractor communicatively coupled to the first sensing device and configured for computing a first difference signal by subtracting the second signal from the first signal;

    a first signal multiplier communicatively coupled to the first signal combiner and configured for computing a first exponentiation signal using the first sum signal;

    a second signal multiplier communicatively coupled to the first signal subtractor and configured for computing a second exponentiation signal using the first difference signal; and

    a second signal subtractor communicatively coupled to the first and second signal multipliers and configured for subtracting the first exponentiation signal from the second exponentiation signal to obtain a first reference signal.
