The Calibration of I/Q Bi-channel Mismatch in Wideband Receiver
摘要
Abstract
Due to diversified factors, I/Q mismatch generates and the performance of receiver become worse. This paper analysises the method to estimate the I/Q mismatch errors, and a calibration method of digital correction based on FIR filter for wideband digital receiver is proposed. The influence of the number and the position of calibration frequencies on the system is analyzed. The simulation demonstrates that this method can improve the performance of wideband receiver effectively.关键词
