这份报纸调查在观察与多重时间延期为线性分离时间的系统弄平问题的定点。考虑的线性分离时间的系统有 l + 1 条产量隧道。一个人是即时观察，其他人被耽搁。包含递归的算法和非递归的算法的定点 smoothers 被没有依靠系统扩大途径，使用革新分析理论设计。另外，这进一步被显示出定点的设计更光滑与象原来的系统的一样的尺寸沿 1 个 Riccati 方程下来到解决 l + 。

英文摘要：

This paper investigates the fixed-point smoothing problems for linear discrete-time systems with multiple time-delays in the observations. The linear discrete-time systems considered have 1 ＋ 1 output channels. One is instanta- neous observation and the others are delayed. The fixed-point smoothers involving recursive algorithm and non-recursive algorithm are designed by using innovation analysis theory without relying on the system augmentation approach. Also, it is further shown that the design of fixed-point smoother comes down to solving 1 ＋ 1 Riccati equations with the same dimensions as the original systems.
