Abstract

Non-linear distortions, called glitches, occur in radio receivers when automatic gain control (AGC) is employed for regulating the dynamic range of the received signal. It is proposed to determine (S) the occurrence of a glitch caused by operation of the AGC mechanism, and estimate (S) a representation of how energy of a signal transient associated with the glitch is transferred by digital filter(s) in the receiver. The radio signal is then detected (S) at least partly based on the estimated representation. In this way, the adverse effects of the glitch can be mitigated and detection of the desired signal can be significantly improved. This also means that the link performance will be significantly improved.
