| 摘 要： | 由模拟器件构成的超宽带正交解调接收机不可避免地存在系统失真 ,这些失真的存在有时会严重影响系统的性能。仔细分析了幅度失真、相位失真、幅相不一致性等对接收机性能的影响 ,提出了数字域校正的方法。通过计算机仿真 ,表明了该方法的可行性。最后 ,对某超宽带正交解调接收机的实际测量结果的数字校正 ,验证了这种方法的有效性。

| Abstract: | The system distortion is inevitable in ultra-wide-band quadrature demodulation receiver consisting of analog devices. The effect of amplitude distortion, phase distortion, amplitude and phase error on the performance of receiver is discussed in this paper, and a method of digital correction is proposed. Finally, the validity of digital correction is verified by simulation and practical measurement of a UWB quadrature demodulation receiver. |
