Method and apparatus in a wireless communication device for mitigating a received power overload

摘要

A power measurement element (106) measures (302) the wide-band received signal power of a receiver (102), and a wide-band AGC system (108) transfers (306) receiver gain control from an on-channel AGC system (110) to the wide-band AGC system, when the wide-band received signal power exceeds a pre-programmed threshold for longer than a pre-programmed delay time. The wide-band AGC system is arranged and programmed to decrease (308) a front-end gain of the receiver through a plurality of gain steps of a pre-programmed size (208) applied at a pre-programmed rate until the received wide-band signal power falls below the pre-programmed threshold.
