Abstract: A method of communicating over a network for wireless communications is disclosed. The method transmits encoded data from a source device to a destination device via a single path up through a plurality of wireless paths using a random frequency hopping tuning pattern for wireless communications, and pseudo-randomly varies dwell times of the frequency hopping tuning pattern over which the data is transmitted. The network uses forward-error correction coding redundancy within a data burst to allow recovery of corrupted data in any partially jammed hop of the transmitted data.

Abstract: A method and system for communicating using pulsed radar signal data links is disclosed. The method comprises encoding downlink data with a signature sequence as a secondary function onto a continuous wave pulse signal having a primary function at a master device. The data-encoded pulse signal from the master device is interpreted at one or more slave devices configured to receive the pulse signal within a first communications bandwidth of the primary and secondary functions. The master device synchronizes returning communication transmissions from each of the one or more slave devices for the secondary function within a prescribed return interval of the primary function.

Abstract: A method and apparatus for enhancing the resolution of an analog-to-digital converter. The method uses the addition of a second analog waveform to a first analog signal which is to be converted. When the composite signal is converted to digital form, this enhances the effective resolution of the A/D converter with respect to the first signal. Integration of the composite digital signal causes the effects of the second waveform to average to zero. The result is an enhanced resolution signal without undesired effects of the added second signal.
