ABSTRACT:
A frequency hopping communication system whose transmitters and receivers after synchronization hop over a frequency series of a first type. To synchronize the transmitters and receivers, sync data from a transmitter are transmitted and received in portions spread over a frequency series of a second type in order to protect the transmission of sync data against jamming and eavesdropping.
