A calibration scheme based on theory of frequency sampling was proposed to compensate the non-idea characteristics of analog filter in RF front-end. Theoretical basis of two modules in this scheme were discussed, namely the measurement of sample values and calculation of tap coefficients. At last, analysis of actual system experimental result was given.%针对短波通信系统射频前端模拟滤波器存在的非理想特性,设计了一种基于频率抽样理论的校正方案.该方案由抽样值测量、抽头系数计算及滤波等部分组成.对该设计的理论基础做了详细的描述,并对应用于实际接收系统中的测量结果进行了分析说明.
