Problems solved by technology

However, such sensors and antennas will take up a lot of space, which is undoubtedly a waste of resources for the limited space of electronic equipment
In addition, the closer to the antenna, the greater the specific absorption rate, which is also the place that best reflects electromagnetic wave radiation. If the distance between the sensor and the antenna is too far, the SAR cannot be accurately obtained.

Description

technical field [0001] The invention relates to signal processing technology of electronic equipment, in particular to an information processing method and electronic equipment. Background technique [0002] With the advancement of communication technology, electronic devices with mobile communication functions (such as mobile phones, PADs, etc.) are becoming more and more popular. Electromagnetic wave radiation generated by electronic devices in the communication process will cause harm to the user's body. Therefore, the specific absorption rate (Specific Absorption Rate, SAR) generated by the antenna is strictly regulated in the existing technical specifications of mobile communication. Generally, the way to reduce SAR is to use sensors to sense whether there is human tissue approaching, and accordingly control the electromagnetic wave radiation generated by the antenna within the acceptable specific absorption rate range. [0003] At present, in order to avoid the influe...
