Fast hopping correlator-based transceiver

A frequency hopping receiver, comprising:

• one or more antennas that are configured to receive incoming wireless signals that include one or more frequency-hopped data signals and one or more narrow-band interference signals;
• a receiver digital oscillator that is configured to provide receiver oscillation signals at one or more frequencies as a function of a receive hopping code;
• and
• receiver correlation circuitry that is communicatively coupled to the receiver digital oscillator and to the one or more antennas, wherein the receiver correlation circuitry is configured to:
• de-spread the one or more frequency-hopped data signals to generate de-spread data signals;
• spread, based on the receiver oscillation signals, the one or more narrow-band interference signals over a plurality of receive channels to create frequency-hopped interference signals;
• and
• filter out the frequency-hopped interference signals from the de-spread data signals.

A method of providing in-band rejection of interference signals, the method comprising:

• receiving, by one or more antennas, incoming wireless signals that include one or more frequency-hopped data signals and one or more narrow-band interference signals;
• providing, by a receiver digital oscillator, receiver oscillation signals at one or more frequencies as a function of a receive hopping code;
• receiving, by receiver correlation circuitry that is communicatively coupled to the receiver digital oscillator and to the one or more antennas, the receiver oscillation signals provided by the receiver digital oscillator;
• de-spreading the one or more frequency-hopped data signals to generate de-spread data signals;
• spreading, based on the receiver oscillation signals, the one or more narrow-band interference signals over a plurality of receive channels to create frequency-hopped interference signals;
• and
• filtering out the frequency-hopped interference signals from the de-spread data signals.
