    摘要： Methods and apparatus for mitigating a platform-emitted interference to a modem in a device. A processor may detect, based on an application or a use case running on the device, a need to implement an interference mitigation measure by the modem to mitigate an interference caused by an interference signal emitted due to operation of other platform components in the device. The processor sends a message to the modem based on an interference profile stored in the device to implement the interference mitigation measure by the wireless modem. The interference profile includes frequency, bandwidth type, and bandwidth of an interference signal, or a filter number to be used for interference mitigation. The modem may perform an interference impact analysis based on the message and perform an interference mitigation measure to mitigate an interference to the received signal based on the interference impact analysis.

    摘要： This application relates to the field of communication technologies, and discloses an anti-interference electronic device and an anti-interference method. The electronic device includes a first transmission circuit and an anti-interference circuit. The first transmission circuit includes a first receive end, a first transmit end, and a first conversion module. The first conversion module is configured to convert a first-type signal in a signal received by the first receive end into a second-type signal to be sent by the first transmit end. The anti-interference circuit is configured to cancel the second-type signal in the signal received by the first receive end. The cancelled second-type signal is sent by the first transmit end and then received by the first receive end. In the technical solution of this application, the anti-interference circuit is designed in the electronic device to accurately cancel an interference signal in a Wi-Fi link, so that anti-interference can be better implemented when a configured bandwidth of an NR is large. This improves demodulation performance of the Wi-Fi link, and improves communication link quality and user experience.

    摘要： The disclosure describes techniques to filter unwanted noise from feedback signals of an electrical machine. An electrical machine may receive AC power from an inverter and circuitry in the inverter may cause noise on the AC power signals to the electrical machine. The noise may couple to sensors for the electrical machine and cause noise in the sensor output signals. The sensor output signals may provide feedback for a closed loop control system for the electrical machine and noise may impact the closed loop operation. Also, the noise in the feedback signals may cause electromagnetic compatibility (EMC) issues, either by direct radiated emissions or by coupling to other circuits in the vehicle wiring harness as the feedback signals travel from the electrical machine. The techniques of this disclosure may include filter circuitry located near or inside the electrical machine that filters out the unwanted noise in the feedback signals.
