- 基于Simulink的DPSK的通信系统仿真 Simulink 是MATLAB提供的实现动态系统建模和仿真的一个软件包，它让用户把精力从编程转向模型的构造，为用户省去了许多重复的代码编写工作；Simulink 的每个模块对用户而言都是透明的，用户只须知道模块的输入、输出以及模块的功能，而不必管模块内部是怎么实现的，于是留给用户的事情就是如何利用这些模块来建立模型以完成自己的仿真任务；至于Simulink 的各个模块在运行时是如何执行，时间是如何采样，事件是如何驱动等细节性问题，用户可以不去

- Simulink 的每个模块对用户而言都是透明的，用户只须知道模块的输入、输出以及模块的功能，而不必管模块内部是怎么实现的，于是留给用户的事情就是如何利用这些模块来建立模型以完成自己的仿真任务；至于Simulink 的各个模块在运行时是如何执行，时间是如何采样，事件是如何驱动等细节性问题，用户可以不去关心，正是由于Simulink 具有这些特点，所以它被广泛的应用在通信仿真中，利用Simulink 强大的工具箱和其建模的优势建立了常用的DPCM数字电话通信系统仿真模型，对该通信系统进行了模型构建

- 7 号信令的特点是：信令速度快，具有提供大量信令的潜力，具有改变和增加信令的灵活性，便于开放新业务，在通话时可以随意处理信令，成本低。目前得到广泛应用。CCITT 自1980年提出7 号信令黄皮书，先后多次修正，至1993 年提出白皮书。 中国7 号信令规范于1990 年8 月实施，该规范是以CCITT 于1988 年颁布的蓝皮书为参考制订的，只在电话网中使用，即只采用了消息传递部分（MTP）和电话用户部分（TUP） -SS7 is characterized by: signaling

- ISDN 的业务种类很多,而且其业务能力是发展的。ISDN 的业务在进行分类 时遵循了以下原则： (1)ISDN 应该能够继续提供现有网络， 包括公用交换电话网、分组数据网、用户电报网等所能够提供的用户需求的所有业务； (2)ISDN 的业务应该考虑到ISDN 与现有网络的互通与兼容； (3)ISDN 的业务需要充分估计到用户的新业务需求，包括不久的将来可能会出现的新的通信需求。 ISDN 电信业务可以分为提供基本传输功能的承载业务(bearer services)和包含终端
