ABSTRACT:
A frequency hopping data communication system for a bidirectional communication system is described in which improved operation in a jamming and/or fading environment is provided. A pseudo-noise code generator is utilized to provide a random sequence of ON-OFF pulses representative of binary numbers which cause a microprocessor to select data at a desired frequency which is then coupled to a frequency synthesizer to provide a controllable frequency and an improved anti-jam capability in both a receiver and transmitter.
