METHOD AND SYSTEM FOR CONTINUOUSLY COMPENSATING FOR PHASE VARIATIONS INTRODUCED INTO A COMMUNICATION SIGNAL BY AUTOMATIC GAIN CONTROL ADJUSTMENTS

摘要

A communication system (100) including an automatic control (AGC) circuit (105), a receiver (110), an analog to digital (ADC) converter (115) and an insertion phase variation compensation module (120). The AGC circuit receives and amplifies communication signals (150). The gain of the AGC circuit is adjusted. The AGC circuit outputsan amplified signal (145) to the receiver which, in turn, outputs an analog complex signal to the ADC (115). The ADC outputs a digital complex signal to the insertion phase variation compensation module (120) which counteracts the effects of phase offsets introduced into the communication signal due to the continuous gain adjustments associated with the AGC circuit.
