摘要
本文采用不同幅值的三电平伪随机m序列作为输入信号,辨识了离散非线性系统Wiener模型的线性脉冲响应函数和非线性增益系数.同时讨论了参数估计的统计特性及其区间估计,并附有仿真结果.
By using the three-level-pseudorandom-sequences with different amplitudes as input signals, we have identified the impulse response functions of the linear part and the polynomial coefficients of the nonlinear part of the discrete-time Wiener model of nonlinear systems. The statistic properties of the estimated parameters and their tolerable bound are discussed in detail. Some simulation results are included in this paper.
