串口编写程序 VC6请使用 LsCommDemo(for vc6).zip VC7请使用 LsCommDemo(for vc7).zip 作者：Liu_sir VC知识库 http://www.VCKBASE.com 多线程,多接收模式串口类LsComm相关文档 多线程,多接收模式串口类LsComm 作者:Liu_sir 所以参照Delphi中的SpComm设计了一个类CComPort,对CSerialPort进行了2次封装,主要目的是简化串口的使用.使其用简单的代码就可以完成串口通讯的过程.并提供了一个Demo程序演示了CComPort的使用 多线程，多接收模式串口类 LsComm 之二 作者:liu_sir 实现了一个简洁易用的多线程串行通讯接口,可以切换查询和自动接收模式,进行对串口数据收发-Serial programming VC6 use LsCommDemo (for vc6). ZipVC7 use LsCommDemo (for vc7). Zip Author: Liu_sirVC Knowledge http://www.VCKBASE.com multi-threaded, multi-mode serial port to receive the relevant document category LsComm multi-threaded, multi-category serial receive mode LsComm Author: Liu_sir Therefore, in light of Delphi SPComm designed a category CComPort, on CSerialPort a 2 package, the main purpose is to simplify the use of serial port. it simple code to complete the process of serial communication. and provided a Demo program CComPort demonstrated the use of multi-threaded, multi-mode rec

    压缩包有六个文件，分别是绘制圆波导TE波和TM波各模式的横截面场分布、三维静态场分布、三维动态演示。能够绘制的模式有TE波或TM波01-23共2*9种。除截面场分布文件是运行程序后自动生成9种模式分布图外，其余文件是运行后根据提示输入参数（如绘TE11就找到对应的文件，由提示输入1，1即可），参数是模式下标。圆波导模多存在极化兼并，图中可以看出，但是只绘制了余弦情况下对应的场分布（正弦只是旋转了90度）。压缩包里有程序运行的部分结果。时间仓促，结果没来得及仔细核对，有错误希望指出。

伪随机序列在扩频通信、流密码、信道编码等领域有着十分广泛的应用。文通过对伪随机m序列的编码和译码算法进行的MatLab语言仿真，验证了伪随机序列码的编码和译码算法，丰富了伪随机序列的实现方法，并提供了源代码。-Pseudo-random sequence in the spread spectrum communication, stream cipher, in areas such as channel coding has a very wide range of applications. Through the pseudo-random sequence m of encoding and decoding algorithm for the MatLab language simulation code pseudo-random sequence of coding and decoding algorithm, has enriched the realization of pseudo-random sequence method, and provides the source code.
