Abstract
A method of modifying gain tables for the reverse-link communications in a cdma2000 wireless communication network includes the steps of estimating the velocity of a mobile station for a given frame error rate (FER) and data rate, and providing three gains to choose between based on the estimated velocity in order to specify a reverse-link transmit power level. The velocity estimation may be performed using a level crossing technique, a covariance approximation technique, or a Doppler spectrum estimation technique.
