Abstract
Apparatus and method are disclosed for synchronziing the operation of the frequency sensitive devices of two or more transceiver units in a secure, wireless communication system. A fixed frequency pilot signal is generated in a first unit of the system and transmitted to the other units. The encoding noise signal locally generated in each unit is timed by clock pulses derived from the locally available pilot signal. If synchronism between the respective noise signals is lost, the pilot signal is disabled. This causes a reset pulse to be generated in each unit. The action resets each noise generator and restores synchronous operation.
