Claim:
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 (OFDM) starts, wherein an LTE OFDM starting time is determined by using a synchronous frame header (CP) of a received LTE OFDM symbol; 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.
