非线性函数规范化多项式拟合精度分析

Accuracy Analysis Of Normalized Polynomial-Match For A Non-Linear Function

多项式可用于非线性信号的拟合,关键在于求解其各项系数。对于任何非线性函数,文献[1]提出一个规范化的拟合方法。

A polynomial can be used for matching a non-linear function .The key is how to obtain its coefficients .In the paper , a normalized polynomial method for matching any non-linear function is presented. The matching accuracy is affected by the selection of radix point digits and matrix ladders, which is discussed in this paper.
