Abstract: An electronic device may include wireless circuitry having one or more antennas. An antenna ground for an antenna may be formed from two separate conductive ground structures coupled to each other via a conductive interconnect structure. A slot element may be formed in one of the conductive ground structures to reject signals at one or more victim frequencies resulting from spurious signals generated by a non-ohmic contact formed between the conductive interconnect structure and the one of the conductive ground structures. The conductive interconnect structure may overlap and excite the slot element, which serves as an ineffective radiator at the one or more victim frequencies.

Abstract: A transmitter of an electronic device may include one or more intermediate frequency stage circuitries. Processing circuitry may select one or more intermediate frequency stage circuitries of the transmitter that output one or more intermediate frequency signals that cause interference with a signal received by a receiver of the electronic device. The processing circuitry may adjust settings of the one or more intermediate frequency stage circuitries to reduce interference with the signal received by the receiver and store the settings. Subsequently, the processing circuitry may receive an indication of an operational mode of the receiver and apply the settings to the one or more intermediate frequency stage circuitries based on the indication.

Abstract: A technique for reducing interference on conducted RF links involves a determination of active wireless channels in an electronic device. For example, the device can determine whether there are any active cellular, WiFi, and/or Bluetooth channels. If so, any active channels can be removed from a list of possible channels that can be used for generating the RF signals for the conducted RF link. If any idle channels remain available, one or more may be selected for use for the conducted RF link. Those idle channels having a higher offset from any active channels may be given a greater weight in the selection since they should be less likely to be subject to interference. If not, one of the least crowded active channels may be selected for use for the conducted RF link.

Abstract: Techniques described herein are directed toward smart external interference detection and avoidance. An example method includes determining a first received signal strength indicator (RSSI) value of a received first signal across a radio band, wherein the first RSSI value is based at least in part on a second signal transmitted by an interfering device. The first received RSSI value is compared with a threshold value. A first gain adjustment value is determined for a receiver chain of the first computing device and a second gain adjustment value of a transmitter chain based at least in part on the comparison. A first gain of a first amplifier of the receiver chain is adjusted based at least in part on the first gain adjustment value. A second gain of a second amplifier of the transmitter chain is adjusted based at least in part on the second gain adjustment value.

Abstract: The present techniques relate to reducing interference on conducted RF links by utilizing country information to determine where an electronic device is located, and using such information to select sub-bands or channels that are not available for wireless transmission to be used for transmission of signals via the conducted RF links. Because the conducted RF links operate on frequency bands that are different from the frequency bands used for wireless communications in a given country, there is less likelihood that wireless communications will create interference in the signals being transmitted via the conducted RF links.

Abstract translation: 用于减少对传导RF链路的干扰的技术涉及确定电子设备中的主动无线信道。 例如，设备可以确定是否存在活动的蜂窝，WiFi和/或蓝牙信道。 如果是这样，可以从可用于生成用于传导RF链路的RF信号的可能信道的列表中移除任何活动信道。 如果任何空闲信道保持可用，则可以选择一个或多个用于所传送的RF链路。 那些具有比任何活动通道偏移较大的空闲信道可能在选择中给予较大的权重，因为它们应该不太可能受到干扰。 如果不是，可以选择最不拥挤的活动频道中的一个用于传导的RF链路。
