1. A method of gain equalization based on a wide-band multi-carrier base station, comprising the steps of:

  • a) calculating a gain of respective carriers at an output port of a digital to analog converter (DAC) and normalizing to obtain a first gain correction factor table with a plurality of respective first gain correction factors;

    b) testing the gain of the respective carriers in a radio frequency portion and normalizing to obtain a second gain correction factor table with a plurality of respective second gain correction factors;

    c) storing the first and second gain correction factor tables; and

    d) looking up a first gain correction factor from the first gain correction factor table and a second gain correction factor from the second gain correction factor table corresponding to each of the carriers, and multiplying the first gain correction factor with the second gain correction factor, and using multiplied result as a gain-adjust-coefficient of the respective carrier.
