Abstract
In a wireless receiver, an estimated decision boundary for use in detecting symbol values from one group of combined received symbols is calculated based on a estimated traffic-to-pilot channel scaling ratio or an estimated decision boundary corresponding to another group of combined received symbols. By properly combining the information derived from the latter group of combined received symbols with channel estimation information for the former group, a decision boundary estimate for the former group can be obtained without the use of amplitude or power information for the latter group of symbols.
