Digital processing for co-site interference mitigation

摘要

A radio system providing long-range radio communications in the presence of a co-located high power jammer or other radio transmitter that is operating in a frequency band overlapping the communications transmit/receive band. The system collects sample signals from co-located overlapping radio. It down-converts the sample signal and the receive radio signal, digitizes the two signals, and utilizes a computer processor to cancel the sample signal from the receive radio signal to output a mitigated output signal.
