Abstract
The invention provides a receiver comprising an input end, an Rx-chain with at least one regulating means and an output end. The receiver further comprises a feedback loop in the Rx-chain, the regulating means arranged for providing a higher or lower gain setting. The feedback loop comprises an AGC Multilevel threshold detector unit, AMU. The AMU comprises at least one Low Multilevel Threshold Detector, LMTD, and the LMTD comprises at least two threshold detectors, each detector having an associated low threshold level and detection interval, the length of the detection interval being shorter the lower the low threshold level is arranged to be set. The higher gain setting being arranged to be initiated through the feedback loop when the absolute level of an AGC input signal has been below at least one of the low threshold levels during the entire detection interval associated with that low threshold level. The invention also provides a communication system comprising the receiver, an AGC Multilevel threshold detector Unit (AMU) and a method to adjust the gain in a receiver.
