To clarify the improvement of anti-jamming performance of the communication system by adaptive interference cancellation(AIC),this paper analyses the influence of external interference,es-pecially that of transmitted output noise interference and environment noise interference,on the per-formance of the receiving system when it works in an actual environment,and tests the performances of a transceiver system by using an AIC on an experimental platform and an actual working platform respectively.The experiments show that the noise near the interference frequency can be significantly reduced when using the AIC,and the noise far away from the interference frequency has not obvious change.The experimental results verify the correctness of theoretical analysis.%为阐明自适应干扰对消技术(AIC)对通信系统抗干扰性能的改善程度,分析了使用对消装置的收发系统在实际工作条件下,外部干扰信号特别是发射机输出噪声干扰和背景环境噪声干扰对接收系统性能的影响.在此基础上,针对某型通信系统分别在模拟实验平台和实际工作平台进行了相关实验.实验数据表明:使用对消装置后,频谱仪接收到的噪声功率在远离干扰频率处无明显变化,在干扰频率附近则有显著降低,由此验证了理论分析的正确性.
