Abstract

Adjusting a power control setpoint to compensate for imperfect signal detection in a communication channel capable of discontinuous transmission (DTX). The power control setpoint is compensated for false detections by adjusting the power control setpoint by a dynamically determined setpoint back off amount upon detection of a Good Frame. The amount of the setpoint back off is a function of the measured signal quality of the detected Good Frame and the number of Erasure indications received immediately preceding the Good Frame indication. In an alternative embodiment, an expected FER is scaled by one minus the probality of false DTX to compensate for the effects of false DTX. A state machine is implemented to compensate the setpoint for the effects of false erasure. The state machine estimates a number of false erasures by evaluating erasure detections in relation to consecutive DTX detections in the absence of good frame detections.
