摘要
针对用于解决无线通信系统与其他用频设备之间电磁兼容(EMC)问题的LMS自适应干扰对消算法,利用System Generator对其进行了建模和仿真,在定频情况下证明了模块的正确性和有效性.将其应用到所建立的跳频通信系统中进行仿真,得到了不同定点数精度下信噪比-误码率曲线,据此分析了不同定点数精度的算法对抗干扰效果的影响,认为只有定点数精度高于阈值时,抗干扰模块才能对通信系统的通信质量有较大提升.
Aimed at the LMS adaptive interference cancellation system for solving the EMC problem when wireless communication systems are used with other using-frequency equipment,the LMS adaptive cancellation algorithm is built and simulated on System Generator,and the effect and validity of the module is verified under the condition of constant-frequency.Then,it is applied to the frequency hopping communication system,the SNR-SER curve is achieved in different fixed-point number precisions.Finally,the influence of the fixed-point number precision is analyzed,and the conclusion is reached that the module can improve the communication quality effectively in the conditional fixed-point number precision.
