基于 M序列和逆 M序列 ,提出了多维逆 M序列发生器的结构形式。多维逆 M序列近似周期白噪声 ,无直流分量 ,各维序列之间互不相关。文中研究了多维逆 M序列的性质 ,给出了自相关函数的计算公式。通过使用多维逆 M序列 ,将多变量系统参数辨识简化为各通道对应的单变量系统参数辨识。多维逆 M序列具有很好的推广应用价值。
Based on M sequence and inverse M sequence, the structure of multi-dimensional inverse M sequence generator is proposed. Multidimensional inverse M-sequence approximate periodic white noise, no DC component, each dimension sequence unrelated to each other. In this paper, the properties of multidimensional inverse M sequences are studied, and the formula of the autocorrelation function is given. By using multidimensional inverse M-sequence, multivariable system parameter identification is simplified to the univariate system parameter identification corresponding to each channel. Multidimensional inverse M sequence has a good promotion and application value.
