Abstract
An example frequency hopping transceiver includes one or more antennas, a transmitter digital oscillator, transmitter correlation circuitry, a receiver digital oscillator, and receiver correlation circuitry. The transmitter correlation circuitry is communicatively coupled to the transmitter digital oscillator and to the antennas, and is configured to spread, based on transmitter oscillation signals, transmit signals over transmit channels to create frequency-hopped transmit signals that are provided to the antennas. The receiver correlation circuitry is communicatively coupled to the receiver digital oscillator and to the antennas, and is configured to: de-spread the frequency-hopped data signals; spread, based on the receiver oscillation signals, one or more narrow-band interference signals included in received signals over a group of receive channels to create frequency-hopped interference signals, where the receive channels are orthogonal to the transmit channels; and filter out the frequency-hopped interference signals from the de-spread data signals.
