摘　　要：为了分析矢量调制器对干扰抵消器性能的影响,基于测量矢量调制器幅度相位的方法研究了其特性。在实测数据的基础上分析了双极性电调衰减器的缺陷对矢量调制器和干扰抵消器性能的影响,并提出了引入可调移相器的改进方法。理论分析和实验数据表明文中提出的方法有助于提高干扰抵消器的抵消性能。In order to analysis the performance of the vector modulator impacting on the cancellation performance of the interference canceller, the paper researches its performance based on measure its amphtude and phase. And, based on the experiment result, the paper has analyzed the hmitation of the bipolar attenuator maybe an influence factor to the interference Cancellation, and proposed an improved method based on the adjustable phase shifter. The theoretically analysis and experiment result shows the improved action is very efficiency in boosting a high performance Interference Canceller.
