PREDICTIVE POWER CONTROL IN A DIGITAL DIVERSITY RECEIVER

摘要

A method (300) and an apparatus (202) for a digital diversity receiver having a first receiver branch (204) and a second receiver branch (206) for adjusting a receiver power control loop during a radio frame (100) of a known length are provide. The digital diversity receiver (202) receives a first signal (208) through the first receiver branch (204) during the radio frame (100), and receives a second signal (210) through the second receiver branch (206) during a portion of the radio frame (106, 110). The second signal (210) originates from a common original signal (212) as the first signal 208. The digital diversity receiver (202) evaluates (308) a receiver power control parameter for the first interval (106) based upon the first signal (208) and the second signal (210), and compensates (310) the receiver power control parameter with an offset value for the first interval (106). The compensated receiver power control parameter is then applied (312) to the receiver power control loop during the first interval.
