同步通信

Since the conditional Lyapunov exponents of its linear subsystem are all negative, the linear subsystem is synchronizable and the new chaos generator can be used for chaotic communication.

由于它的线性子系统的条件李雅普诺夫指数均为负，因而是可同步子系统，能够用于混沌保密通信。

Chaotic signals' some characteristics make t1hem have natural invisibility, for example, they have nonperiodic continuous broader frequency spectrum and they are similar to noise. So, recently, chaotic synchronization and its application for secure communications attract wide interest.

混沌信号的非周期性连续宽带频谱，类似噪声的特性，使它具有天然的隐蔽性，因此近年来混沌同步及在保密通信中的应用受到了广泛的关注。

The standards specify several types of end user access circuits, each of which involves one or more B channels and one D channel. The B channels are for circuit-switched user communications, and the D channels are primarily for signaling and control (e.g., on-hook and off-hook signaling, ringing signals, performance monitoring, synchronization and error control).

该标准详细列出了几种终端用户电路类型，每一种类型包含一个或多个B信道以及1个D信道。B信道用于电路交换用户通信，D信道主要用于信令和控制（例如挂和摘机机信令、振铃信号、性能监控、同步以及错误控制）。

Multipath is the main character of the mobile communication system. Multipath signal of the target user turn out to be the ISI of the main path signal, multipath signal of the other users cause severe MAI since the orthonormality among the spreading codes is destroyed.

多径干扰是移动通信系统中的常见干扰，目标用户的多径信号对主路径信号引入了码间干扰，其它用户的非同步路径信号由于破坏了扩频序列的正交特性而导致了强的多址干扰。
