A wireless signal amplification system including amplification apparatus (6) consisting of numerous different amplifiers (61 to 6n) which are distributed in an analogue processing chain (4). Also, a converter (12) for converting analogue signals into digital signals which, at input, are connected to the outlet of the analogue processing chain (4) and, at output, are connected to at least the gain control circuit (16) of the amplification apparatus (6) according to a value that is representative of a characteristic of the wireless signal (1). In this way, sampling of the wireless signal (1) by the converter (12) is optimized. The gain control circuit (16) establishes an average gain control signal (18), and also has, for each of the amplifiers (61 to 6n), a device for calculating an individual gain control signal (20i to 20n) according to a transfer function (H1 to Hn) which is specific to each amplifier and which is applied to the average gain control signal.
An amplification system for a wireless signal (1) comprising amplification means (6) consisting of a plurality of distinct amplifiers (61 to 6n) distributed within an analogue processing chain (4), and means (12) for converting analogue signals into digital signals linked at input, to the output of said analogue processing chain (4) and at output, at least, to means (16) of control of the gain of said amplification means (6) as a function of a value representative of a characteristic of said wireless signal (1) so as to optimize the sampling of said wireless signal (1) by said converter (12), said control means (16) comprising means for establishing a mean gain control signal (18), characterized in that said control means (16) furthermore comprise, for each of said amplifiers (61 to 6n), means for calculating an individual gain control signal (20i to 20n) according to each amplifier's own transfer function (H1 to Hn) applied to said mean gain control signal.
