This thesis proposes a novel method of retiming E1 signal of the SDH output and using it as a reference synchronization signal for Trunking Gateway. The proposed retiming method can generate the E1 signal of TG input in comply with the maximum relative time interval error requirement of 52.5ns specified in the PRC-Generation standard. The method successfully reduces the E1 signal error level to a smaller margin of 300ns than that of the PRC-output standard.

本论文提出将同步数位阶层输出E1信号做时序重整，做为中继闸道器的做参考同步信号；这样可使输入中继闸道器的E1信号在最大相对时间间隔误差达到主参考时钟产生的52.5奈秒标准；更能让中继闸道器输出的E1信号，由超出同步数位阶层自由振荡4.6微秒，改善到低於主参考时钟输出的300奈秒标准。

Firstly, a class of affine nonlinear systems are considered. The single-layered neural networks are used to approximate the nonlinear functions of the systems. Stable adaptive control algorithms are presented based on system states feedback and system output feedback respectively. The boundary of the tracking error is guaranteed. Then, by using the technique of input-output linearization, the stable adaptive control method for general nonlinear systems is proposed. Finally, the effectiveness of the proposed adaptive control algorithms are verified through the simulation researches for the control of robot manipulator.
