摘要：
A receiver, or base station, may calculate the signal quality improvement based on a change in a diversity control parameter, for example, a phase difference or a power ratio among two or more antennas, by comparing a received signal power level to an expected power level, assuming no change in fading characteristics at the previous timeslot. This method may increase the amount of information communicated between the base station and the mobile unit, and may reduce feedback response time and/or provide for more efficient feedback for transmit diversity systems.
