Abstract:
A method for performing frequency hopping communication with another party over an available spectrum of frequencies, the spectrum being arranged into a plurality of segments, each of the segments comprising a subset of the available spectrum including multiple possible hopping frequencies, the method comprising the steps of:(a) receiving data over a sequence of hopping frequencies, each of the hopping frequencies being part of one or more used segment(s) from the plurality of segments,(b) identifying an error in the received data and an erred segment in which the error occurred, and modifying an error value associated with the erred segment accordingly;(c) replacing the erred segment with an unused segment from the plurality of segments to attempt communication over a less error prone segment, when the error value for the erred segment reaches at least a predetermined threshold; and(d) notifying the other party of the unused segment which has been newly selected.
