METHOD AND DEVICE OF GAIN EQUALIZATION BASED ON WIDEBAND MULTI-CARRIER BASE-STATION

摘要

The present invention relates to a method and device of gain equalization based on wideband multi-carrier base-station. It adopts calculating or testing in advance respectively nonuniformity between analog intermediate frequency and radio frequency and keep in two tables. Before Operation, the corresponding correct value are found out from the table in accordance with IF frequency and RF frequency of each carrier during the initialization. The specific correction is performed in a multiplier before the value are inserted into a digital up-converter. It can equalize or correct the inconsistence with regard to commom channel of transmitter and every characteristic of carrier amplitude frequency by changing gain-adjust-coefficient of every carrier without modifying any hardware and depravation specification. It is capable to improve the consistence of every carrier-gain and reduce the consumption of resource.
