  • Patent number: 4807248
    Abstract: There is disclosed a technique for providing resynchronization for message reception in digital transmission systems, and particularly in digital frequency hopping systems employing data framing techniques. In the transmission of framed data using known digital techniques for frequency hopping systems, synchronization is provided in frames preceding the message frames transmitting digital data. In addition, resynchronization information is transmitted in subsequent frames which are interspersed with data frames including the message data. A predetermined number of frames is set to provide all the resynchronization information so that once those frames have been detected, a receiver will have acquired resynchronization during message transmission. This technique allows improved signal acquisition by providing an opportunity following the first conventional synchronization frame to acquire synchronization or to reacquire synchronization during message transmission.
