The present invention is related to a method to provide an automatic gain control (AGC) in a receiver structure, comprising the following steps: multiplying a received analogue signal with a predetermined gain setting to obtain an amplifier output signal, sampling the amplifier output signal, estimating the energy in the samples, calculating the average energy, and the further steps of computing the percentage of clipped samples, calculating the target energy value based on the average energy and the percentage of clipped samples and the gain setting, and applying the updated receiver gain setting. <IMAGE>
