Abstract
A method and system that enables the changing of the gain in a closed loop (e.g., self-configuring) telecommunications system based on the age of the available measurements. A high gain is used when measured data are “fresh”, so as to obtain a good performance (e.g., a fast response) for the telecommunications system. The gain is then reduced when the age of the measurements increases. The decreased gain results in a slower system response, but this is a desirable result in order to preserve stability. The system and method may be applied, for example, in many mobile telecommunications systems (e.g., GSM, WCDMA, etc.). In one embodiment, the system and method of the present invention modify the closed loop gain in an adaptive fashion and use one or more fuzzy membership functions for specifying what is meant by “fresh” measurements.
