FIR Model Identification: The Algorithms Based on the Polynomial Interpolation

采用多项式插值方法辩识FIR模型 ,通过插值方法引入一转换矩阵W ,实现从FIR模型参数序列 {hi}到压缩FIR模型参数序列 {cj} 之间的转换 ,从而减少了脉冲响应待辨识参数 ,简化了辨识过程 ,提高计算速度。仿真实验表明该算法快速。

This paper adopts the ploynomial interpolation to identificate FIR Model, inducts a transitive matrix W and realizes the transition from FIR model parameter sequence \%{h\-i}\% to compessed FIR model parameter sequence \%{C\-j}\%. Simulation studies demonstrate the Algorithms is fast,compact and precise.
