摘要 全数字接收机中已有的拉格朗日立方内插滤波器Farrow结构采用固定的实现系数,在对高效调制信号进行解调时误码率较高.在此基础上,经过大量实验,设计了一种基于模糊推理的内插滤波器,根据分数间隔μ的变化,自动控制滤波器的实现系数.仿真和实验结果表明,改进后的内插滤波器降低了误码率,得到了良好的效果. Because of using changeless coefficients,the existing Farrow structure of Lagrange interpolation filter has a high bit error rate for the demodulation of high effective modulated signals.By a mass of experimentation,an interpolation filter base on fuzzy inference is designed.It can control the coefficients of filter with fractionally spaced change.Simulation and experimentation results show that the improved interpolation filter reduces bit error rate.So the good effect is gained.
