ABSTRACT:
An enhanced frequency-agile radio for avoiding undesired signal energy, based on a prediction, by scanning an available radio spectrum, measuring a receiver output, identifying an occupied portion of the available spectrum, predicting a level of undesired signal energy in a future scan, and storing the prediction. Enhancements provided by the frequency-agile radio include lowered implementation complexity appropriate for very low cost receivers and transceivers, reduced size due to elimination of larger components allowing for physically small pocket pager applications, increased anti-jam performance appropriate for wide area networks, increased receiver sensitivity and frequency tracking desirable for voice applications, enhanced signal coding error tolerance allowing operation within congested portions of the radio band and additional signal verification means which allow correct data reception from thousands of concurrently operating, collision prone transmit-only devices such as power utility meters and long range security systems.
