Abstract:
1. Procedure for the removal of the DC component inherent in any radio frequency chain within a radio frequency reception device composed of at least one analogue stage, said analogue stage comprising a multiplicity of analogue components likely to insert a DC component in the signal passing through the stage, said stage comprising a multiplicity of compensation points, a DC compensation signal obtained from the analogue-digital conversion of a compensation value being added to each compensation point, all these compensation points forming a compensation vector, the addition of all the signals to the compensation points aiming to cancel the said DC component inherent to the radio frequency chain being measured at the end of the said analogue stage, which is characterised in that it comprises the following steps: a) a computation step ( b) a computation step ( c) a computation step ( d) a computation step ( e) a lowering step (
