Abstract
A calibration method for calibrating a reception chain comprising an input amplifier of an analogue-to-digital converter, and including the following successive steps: determining a rest gain as a function of the average power of the noise present on a digital signal from said converter; and setting the gain of the input amplifier at said rest gain when the average power of said digital signal is lower than a first threshold.

A calibration method for calibrating a reception chain comprising an input amplifier of an analogue-to-digital converter, and comprising the following successive steps:
- determining a rest gain as a function of the average power of the noise present on a digital signal from said converter;
- and
- setting the gain of the input amplifier at said rest gain when the average power of said digital signal is lower than a first threshold,
- wherein the gain is adjusted by adding a gain adjustment increment determined as a function of the average power of the digital signal when the average power of the digital signal is greater than a second threshold.
