<P>PROBLEM TO BE SOLVED: To provide a transmitter architecture for a communications system of high performance, which consumes less electric power and which requires low cost. <P>SOLUTION: There is provided a method for adjusting signal gain in a transmitter having a first gain element and a second gain element, in which the first gain element responds to an asynchronous first update clock and the second gain element responds to an asynchronous second update clock. The method comprises: receiving determinations for first and second gain transmission characteristics and a first gain setting value for the first gain element and a second gain setting value for the second gain element; adjusting the second gain setting value with a particular gain offset value based on the first gain setting value; determining a linearized gain setting value corresponding to the adjusted second gain setting value; adjusting a gain of the first gain element with the first gain setting value; and adjusting a gain of the second gain setting value with the linearized gain setting value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
