Abstract: 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.

Abstract: A method and apparatus of increasing output power of a plurality of carriers of a wide-band multi-carrier base station system utilizes gain adjusting coefficients to adjust output amplitude of the carriers to satisfy the requirement of the wide-band base station system for different number of carriers and output power. The output power of each of or a part of the carriers is increased when the number of carriers is reduced. Under the premise of not modifying the hardware and satisfying the requirement of protocol specification, the wide-band base station system supports different number of carriers by setting software so that the output power of the respective carriers and the coverage of the base station can be increased when the carriers do not operate in a full configuration.
