摘　　要：研究了基于截断Ｖｏｌｔｅｒａ级数和双线性递归差分方程的非线性自适应建模．考虑了ＭＭＳＥ和广义ＭＭＳＥ准则，分析了各种算法的复杂性．分析结果表明，双线性模型在简洁性和计算复杂性方面均优于截断Ｖｏｌｔｅｒａ级数．This paper investigates the nonlinear adaptive modelling using the Volterra series and bilinear recursive difference equations. The MMSE and generalized MMSE criteria are considered. The analysis results show that the bilinear model is better than the truncated Volterra series in algorithm complexities.
