ABSTRACT:
In a communication system, channel operating parameter carrier frequencies are located in the vicinity of data nulls in a data spectrum. The operating parameter carriers are summed with the data signal. At the receiver, the operating parameter carrier frequencies are recovered by demodulation techniques, and the operating parameters are recovered and processed.
