摘要

复杂子采样混频器应用于各种图像抑制接收机中。这些接收机的图像抑制性能主要受到I/Q相位误差的限制。本文提出了一种数字校正技术来纠正这一误差。采用统计方法，利用本地测试信号测量相位误差，并在基带数字域进行校正。高阶仿真结果表明，该方法可将图像抑制性能提高20 dB。

A digital method for the correction of I/Q phase errors in complex sub-sampling mixers

Complex sub-sampling mixers are used in various kinds of image rejection receiver. The image rejection performance of these receivers is mainly limited by I/Q phase error. A digital calibration technique is proposed in this paper to correct this error. The phase error is measured by a statistical method with a local test signal, and is corrected in the baseband digital domain. With this method, the image rejection performance can be improved as much as 20 dB as indicated by high level simulation results.
