Claim:
1. A method comprising: transmitting, at a first point in time, a first transmission vector signal towards an antenna via a feeder cable connected to the antenna; receiving a first reflected vector signal, the first reflected vector signal being a reflection of the first transmission vector signal reflected from a point in the feeder cable; determining a first transformed transmission vector signal by performing a first vector forward transform on the first transmission vector signal; determining a first transformed reflected vector signal by performing a first vector forward transform on the first reflected vector signal; determining a first complex conjugate vector signal based on the first transmission vector signal and the first reflected vector signal; determining a first computed vector signal by performing a first vector inverse transform on the first complex conjugate vector signal; and determining a first sub-vector by performing a windowing function based on the first computed vector signal.
