A method for automatic gain control of a digital receiver, in particular in a TDMA receiver and a device for performing the method

摘要: Method of automatic gain control a digital receiver (1) comprising amplifier means (2). The method comprises the following steps: - sampling at predetermined frequency output signal (s(t)) from said means; processing samples obtained including, for each sample, comparison absolute value this sample respectively to maximum and minimum threshold; adjustment (G) (2) carried out on completion processing, in such way that: * if is outside bracket [-SMAX, +SMAX], reduced by reduction level, several successive samples, number, lie within [-SMIN, +SMIN], increased increase level. Use especially mobile telephony.
