Abstract
A system for receiving an analogue signal e includes amplifying and digitizing the signal in order to obtain a digitized signal en, a power inversion module, the module determining an inversion gain g2, this gain being applied to the digitized signal en, an automatic gain control AGC loop adapting the power of the signal e before digitization, the input signal of the AGC loop being a function of the inversion gain g2.
Claims8
A system for receiving an analogue signal e comprising
- means for amplifying and digitizing said signal in order to obtain a digitized signal en;
- a power inversion module, which reduces the impact of pulsed interference on the signal to be demodulated, said module determining a power inversion gain g2, this gain being applied to the digitized signal en;
- and
- an automatic gain control (AGC) loop adapting the power of the signal e before digitization, wherein the input signal of the AGC loop is a function of the power inversion gain g2.
