Benefits of technology

[0007]Aspects disclosed in the detailed description include adjusting application parameters for interference mitigation. In one aspect, a computing device is provided that employs a control system configured to detect and mitigate electromagnetic interference (EMI) generated within the computing device. More specifically, the control system is configured to detect possible EMI conditions and adjust parameters within the computing device to mitigate such EMI. In this manner, the computing device includes an aggressor application and a victim receiver. The control system is configured to analyze performance tradeoffs based on an acceptable performance level of the aggressor application and performance degradation experienced by the victim receiver. Based on such analyses, the control system is configured to adjust parameters associated with the aggressor application to mitigate the EMI. Thus, the control system provides designers with an additional tool that may reduce the performance degradation of the victim receiver attributable to the EMI.
[0009]In another aspect, a method for mitigating EMI of a victim receiver caused by an aggressor application transceiver is disclosed. The method comprises determining if a victim receiver experiences EMI as a result of a wired interface coupling an aggressor application transceiver to a central processor. The method further comprises determining an acceptable performance level of the aggressor application transceiver based on a performance tradeoff. The method further comprises adjusting one or more parameters from among a plurality of parameters associated with the aggressor application transceiver to mitigate the EMI experienced by the victim receiver and keep the aggressor application transceiver operating at or above the acceptable performance level.
[0010]In another aspect, a mobile device is disclosed. The mobile device comprises an aggressor camera. The mobile device further comprises a central processor communicatively coupled to the aggressor camera via a wired interface. The mobile device further comprises a victim receiver. The mobile device further comprises a control system communicatively coupled to the aggressor camera and the victim receiver. The control system is configured to determine if the victim receiver experiences EMI as a result of the wired interface. The control system is further configured to determine an acceptable performance level of the aggressor camera based on a performance tradeoff. The control system is further configured to adjust one or more parameters from among a plurality of parameters associated with the aggressor camera to mitigate the EMI experienced by the victim receiver and keep the aggressor camera operating at or above the acceptable performance level.
[0011]In another aspect, a non-transitory computer-readable medium having stored thereon computer executable instructions which, when executed by a processor, cause the processor to determine if a victim receiver experiences EMI as a result of a wired interface coupling an aggressor application transceiver to a central processor. The computer executable instructions further cause the processor to determine an acceptable performance level of the aggressor application transceiver based on a performance tradeoff. The computer executable instructions further cause the processor to adjust one or more parameters from among a plurality of parameters associated with the aggressor application transceiver to mitigate the EMI experienced by the victim receiver and keep the aggressor application transceiver operating at or above the acceptable performance level.

Problems solved by technology

This increase in electromagnetic emissions causes electromagnetic interference (EMI) that degrades the performance of other circuitry within the mobile computing device.
Additionally, continued miniaturization of mobile computing devices, combined with increased frequencies, further exacerbates the effects of EMI.

In one aspect, a computing device is provided that employs a control system configured to detect and mitigate electromagnetic interference (EMI) generated within the computing device. More specifically, the control system is configured to detect possible EMI conditions and adjust parameters within the computing device to mitigate such EMI. In this manner, the computing device includes an aggressor application and a victim receiver. The control system is configured to analyze performance tradeoffs based on an acceptable performance level of the aggressor application and the performance degradation experienced by the victim receiver. Based on such analysis, the control system is configured to adjust parameters associated with the aggressor application to mitigate the EMI. Thus, the control system provides designers with an additional tool that may reduce the performance degradation of the victim receiver attributable to the EMI.

Description

BACKGROUND[0001]I. Field of the Disclosure[0002]The technology of the disclosure relates generally to electromagnetic interference (EMI) of receivers, and particularly to mitigating effects of such EMI.[0003]II. Background[0004]Mobile computing devices, such as mobile phones and computer tablets, have become increasingly prevalent in contemporary society. These mobile computing devices are commonly used for a multitude of everyday functions. For example, a mobile computing device may be used to make phone calls or send e-mail messages via a wireless modem. The same mobile computing device may also perform other functions using function-specific hardware applications, such as taking pictures with an integrated camera or viewing a video on an integrated display.[0005]In this regard, each hardware application communicates with a central processor configured to execute instructions related to such functions. More specifically, data and clock signals are exchanged between each hardware a...
