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

摘要

A method and apparatus of gain equalization based on a wide-band multi-carrier base station calculates or tests non-uniformity of a gain of an analog intermediate frequency and a radio frequency in advance and stores corresponding correction values in tables. In an initialization period before operating, the corresponding correction values are looked up from the tables based on the analog intermediate frequency and the radio frequency corresponding to each of the carriers to implement a specific correction in a multiplier of a digital up-converter before interpolation. Under a premise that hardware is not modified and specification is not degraded, the non-uniformity of the amplitude-frequency characteristic of the respective carriers in shared channels of a transmitter is equilibrated or corrected by changing a gain-adjust-coefficient of the respective carriers, thereby significantly improving the consistency of the gain of the respective carriers and reducing consumption of resources.
