A technique for controlling the frequency allocation in the hop sequence of a frequency hopping digital communications system is presented. The hop sequence is initially formed such that consecutive channels are likely to differ substantially in, frequency. Therefore channel substitution commands can be transmitted twice on, consecutive hops without acknowledgement inasmuch as the likelihood of a, broadband noise source blocking consecutive channels is reduced. The number of channels identified as requiring substitution in the hop sequence is monitored, such, that a hop sequence repair operation or communications link termination can be implemented if channel substitution data traffic …

Why it's free to use
- Filed January 2, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 2, 2022.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
