本文研究了当x_t为ARMA序列和线性系统的频率响应函数H(λ)具有可用式(9)表示的有理函数形式的条件下关于式(2)的最优解。文末给出了一个在通讯系统中预滤波对码间干扰的校正效率的计算实例。
In this paper, we study the optimal solution to Eq. (2) under the condition that the frequency response function H (λ) for ARMA sequences and the linear system has the form of a rational function represented by (9). In the end, a calculation example of the correction efficiency of pre-filtering and intersymbol interference in the communication system is given.
