butterworth滤波器，实现高通低通带通的butterworth滤波器

本程序采用直接扩频技术，应用mfsk调制解调技术实现水声系统的仿真，具有抗多径，可靠性高等特点

通信系统仿真应用，卡尔曼滤波器 实现语言：C语言-communications system simulation application, Kalman Filter languages : C language

本程序是一个直接扩频序列仿真包。需要matlab中安装了simulink才可以使用。-This procedure is a direct sequence spread spectrum packet simulation. Need matlab installed can only be used simulink.

hiperlan协议中mac接入仿真，one proposed way for random RCH number-hiperlan agreement mac access simulation, one proposed way for random number RCH

为调试设备编写的RS232转以太网通信软件。 均使用异步通信方式，RS232使用API编写，以太网使用Sockte类。程序中使用了两个独立线程，线程间以消息方式传递数据，本程序中包括：RS232异步通信、Sockte异步通信、用户界面线程、线程间通信。-Equipment prepared for debugging RS232 to Ethernet communications software. Only use asynchronous communication mode, RS232 using the API written in Ethernet using Sockte class. The program uses two separate threads, the threads in the message is transmitted data, this program includes: RS232 asynchronous communication, Sockte asynchronous communication, the user interface thread, communication between threads.
