Abstract
When the frame rate changes from eighth rate to full rate, the power control process increases the .sup.E.sub.b /.sub.N.sub..sub.o target by .DELTA..sub.1. If the frame rate changes from full rate to eighth rate, the power control process decreases the .sup.E.sub.b /.sub.N.sub..sub.o target by .DELTA..sub.2. In both cases, a decision threshold for a Frame Quality Metric is determined. If the Frame Quality Metric is less than the threshold, normal power control is resumed. If the Frame Quality Metric is greater than or equal to the threshold, the newly set target .sup.E.sub.b /.sub.N.sub..sub.o is decreased by A.sub.3. The target .sup.E.sub.b /.sub.N.sub..sub.o is continually decreased by A until the frame rate changes or the target reaches the required .sup.E.sub.b /.sub.N.sub..sub.o , indicated by a bad frame or lower frame quality metric (i.e., lower than the frame quality threshold).
