AUTOMATIC GAIN ADJUSTMENT AND CONTROL METHOD AND DEVICE FOR ELIMINATING INTERFERENCE BETWEEN GSM AND LTE IN MSR RECEIVER

摘要

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.

1. An automatic gain adjustment and control method for eliminating the interference between Global System for Mobile Communication (GSM) and Long-Term Evolution (LTE) in Multi-Standard Radio (MSR) receiver, comprising:
setting, in an MSR receiver, an upper threshold and a lower threshold which are used for starting up gain control function; detecting an Analogue-to-Digital Converter (ADC) power of an ADC of the MSR receiver when LTE Orthogonal Frequency Division Multiplexing (OFMD) starts; comparing the detected ADC power with the upper threshold and the lower threshold respectively; and based on a comparison result representing that the ADC power is larger than the upper threshold or the ADC power is smaller than the lower threshold, starting up the gain control function of the MSR receiver, and otherwise, not starting up the gain control function of the MSR receiver.
