Abstract:
1. A method of detecting the presence of cross-talk between adjacent channels in a communication system, the method comprising the steps of: receiving at least a portion of a first signal on a first channel; receiving at least a portion of a second signal on a second channel, the second channel being on a frequency adjacent the frequency of the first channel; detecting whether cross-talk is present between the first and second channels by processing at least the portions of the first and second signals with combinatorial logic; monitoring at least a portion of a third signal on a third channel so as to detect cross-talk on the third channel, the third channel also being at a frequency adjacent the frequency of the second channel; detecting the direction of the frequency drift of the second channel toward one of the first and third channels by processing at least the portions of first, second and third signals with combinatorial logic.
