METHOD AND APPARATUS FOR ESTIMATING A SIGNAL FADING CHARACTERISTIC |
摘要 |
<p>A method and apparatus for measuring a characteristic of a fading signal received using a two or more branch diversity receiver is presented. This fading characteristic is generally proportional to the speed of the user. In a first embodiment the number of times the antenna branches change in a selection diversity process is counted, and the result is scaled for imbalance between the branches. The output of a fading quality estimator, indicative of the fading and generally proportional to the speed, is thereby obtained.</p> |
