US 11,690,023 B2 · Interference mitigation for portable communication device

Abstract

Methods and systems for mitigating interference between different transceivers in a portable communication device. An electronic control circuit is configured to quantify an electromagnetic isolation between a first transceiver of a portable communication and a second transceiver of the portable communication device based on a detected radio frequency power coupled to the first transceiver from radio frequency signals transmitted by the second transceiver. A mitigation action is selected from a plurality of mitigation actions based on a magnitude of the quantified electromagnetic isolation. The selected mitigation action is then applied to the second transceiver to adjust at least one radio frequency characteristic of the second transceiver.
