Frequency hopping is one of several spread spectrum communication techniques which offer some immunity to jamming as well as some rejection of multipath interference. Synchronization of the frequency hopping transmitter and receiver is necessary in an operating system. This research concerns a method of synchronization whereby the receiver resynchronizes with the transmitter once each frequency hopping cycle. Thus, in most applications clock drift becomes negligible and continuity of data recovery is ensured. This report presents the principles and details of circuit design and operation. Author
