微波BPSK调制器载波抑制技术

Garrier-Leakage Suppression Techniques for Microwave BPSK Modulators

载波泄漏是制约微波BPSK调制器性能的主要因素,大电平载波泄漏导致调制矢量误差,使误码率恶化。文中探讨几种载波泄漏抑制技术,简述其工作原理,并提供实例。

Carrier-Leakage is one of the most severe limiting factors in microwave BPSK modulators,for high carrier-leakage may cause vector-modulation-error and degrade the BER performance. In this paper,we discuss some carrier-leakage suppression techniques, theories and present some design examples.
