Abstract
A method of compensating phase imbalance comprises, detecting power outputs of a first output signal related to a first phase compensation value and of a second output signal related to a second phase compensation value; calculating a first absolute difference between an in-phase value and a quadrature value of the power output of the first output signal; calculating a second absolute difference between an in-phase value and a quadrature value of the power output of the second output signal; determining a minimum difference by comparing the first absolute difference with the second absolute difference; determining an optimal phase compensation value and a suboptimal phase compensation value from the first and the second phase compensation values according to the minimum difference; and obtaining an updated optimal phase compensation value with a binary search algorithm.
