    Abstract: A method and apparatus for measuring a characteristic of a fading signal received using two or more branch diversity receivers (100) is presented. This fading characteristic is 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 (160), and the result is scaled (170) for imbalance between the branches. The output of a fading quality estimator (180), indicative of the fading and generally proportional to the speed, is thereby obtained.
