Abstract:
Disclosed is an energy-saving and environment-friendly device for a communication system equipment, the device includes: a thermoelectric conversion module, arranged on a surface of or in proximity to a high-power module of the communication system equipment, configured to convert thermal energy of the high-power module into electric energy; and an electric power storage device, connected directly to the thermoelectric conversion module or connected thereto via a switch, configured to be charged using electric energy supplied by the thermoelectric conversion module.
Abstract:
The disclosure relates to an automatic gain adjustment and control method and device for eliminating the interference between the GSM and the LTE in the MSR receiver. The method comprises: in an MSP receiver, an upper threshold and a lower threshold which are used for starting up gain control function are set; the ADC power of an ADC of the MSP receiver is detected when LTE OFMD starts; the detected ADC power is compared with the upper threshold and the lower threshold respectively; and based on that the comparison result is that the ADC power is larger than the upper threshold or is smaller than the lower threshold, the gain control function of the MSP receiver is started up, and otherwise, the gain control function of the MSP receiver is not started up. The disclosure can control the LTE and GSM signal power within a certain range.
Abstract:
A phase-detection auto focus method includes: dividing a focus region into a plurality of sub-regions, and respectively calculating a phase difference and a confidence level of each sub-region; performing dynamic matching in a corresponding weight table according to the phase difference and the confidence level of each sub-region, and performing a table lookup to obtain a corresponding weight value; calculating a phase difference and a confidence level of the focus region in conjunction with the weight value; and performing auto focusing according to the phase difference and the confidence level of the focus region.
