Abstract
A method of providing an automatic gain control (AGC) in a receiver structure includes 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, 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 update receiver gain setting.
