| 摘 要： | 在实际的多路复用系统中，当信号通过通信网络进行传输时，时常会发生具有随机性的时滞或数据丢失现象。该文研究当传输信号存在不超过一个采样周期的随机延迟的多路复用系统噪声滤波问题。对多路复用器系统状态空间模型进行改写，并通过扩维的方法解决噪声模型非白的问题，从而建立新的状态空间模型；基于新模型通过采用降维的最优滤波设计方法设计出多速率最优分析滤波器；通过计算机仿真试验，验证新滤波器的有效性。

| Abstract: | In practical system, randomly time - delayed or data - missing situation often occurs when data is transmitted through commtmication network. Based on this case, the noise filter design for the transmission signal existence one - step random time delay transmulfiplexer system is studied. Firstly, state space model of transmultiplexer system is rewrited as well as a new state space model is built by expanded dimension, which is to solve the problem of non - white noise model. And then, based on the new model, mulfirate optimal analysis filter is designed by used of the dimension - reduced design method for optimal filter. Finally, it is confirmed the new filter validity through the simulation. |
