Abstract
A method includes accessing sets of correlation values, each set corresponding to a correlation performed between a number of first samples and a same number of second samples. The sets of correlation values were determined by aligning the number of the first samples with selected second samples and sliding the number of first samples across the second samples to select different sets of the second samples. The first samples are samples of a forward signal transmitted over a cable/connector system to one or more antennas, and the second samples are samples of a reflected RF signal that comprises a reflected version of the forward signal. The method includes determining a maximum value from the plurality of sets of correlation values, and associating the maximum value with a return loss of the cable/connector system. Apparatus, computer programs, and program products are also disclosed.
