Abstract
The method is applicable to a receiver (1) of signals corresponding to packets of digital data transmitted in bursts, which comprises an analogue pickup subassembly (3) connected to a digital processing subassembly (8) by means for converting analogue signals into digital signals (7). Gain adjustment means (5) act on the amplification means (5) in order to alter the power of signals supplied to the conversion means.The method provides a preadjustment of the gain, in the absence of a burst, for detecting the arrival of signals even if they are weak, and an adjustment of the gain as a function of a power value of the signal determined from burst start symbols, as obtained after conversion. This adjustment is dependent on the recognition of symbols scheduled at the start of a burst, it is carried out during a time scheduled for a symbol otherwise left unexploited by the method.
