Abstract :
The whole system distortion is inevitable in I and Q channels of analog circuit because of the existing of amplitude and phase unbalance, the performance of receiving system become worse. Begins with the mathematical deduction, the paper presents an I and Q channels digital correcting algorithm, which is applicable to any kinds of symmetrical windows. This method implements simply and has high correcting accuracy. Finally, simulation results verify the validity of the method
