AUTOMATIC GAIN CORRECTION METHOD AND TRANSMITTER

摘要

An automatic gain correction transmitter includes: an input digital power detecting module (100) for receiving baseband signals, obtaining the digital power value of input signals according to the baseband signals, and outputting the baseband signals; a signal processing module (110) for processing the baseband signals which come from the input digital power detecting module, outputting radio frequency signals; a power outputting module (120) for amplifying and outputting the radio signals which come from the signal processing module, and adjusting the gain of the radio signals according to the digital power value of input signals obtained by the input digital power detecting module, and the digital power value of output signals obtained by the output power digital detecting module; an output power digital detecting module (130) for coupling the radio signals which come from the power outputting module, and obtaining the digital power value of output signals according to the radio signals.
