现有数字信号自动调制识别方法大多只适用于无记忆信号，如PSK、ASK、FSK信号等。将有记忆 信号(MSK信号)和无记忆信号一起考虑，提出了一种改进的数字信号自动识别方法。该方法采用信号的瞬时统 计量作为特征参数，采用多层神经网络作为分类器。计算机仿真表明：当噪声采用高斯白噪声，并且信噪比大于 l5 dB时，识别率高于96％ ；当信噪比不低于l0 dB时，识别率不低于90％。-Existing digital signal automatic modulation recognition methods are mostly applied only to memoryless signals, such as PSK, ASK, FSK signals. Will have a memory signal (MSK signal) and non-memory signal into consideration, an improved digital signal automatic identification method. This method is the use of the instantaneous signal statistics as a characteristic parameter, the use of multi-layer neural network as classifier. Computer simulation shows that: When the noise using Gaussian white noise, and signal to noise ratio greater than l5 dB, the recognition rate is higher than 96 when the signal to noise ratio not less than l0 dB, the recognition rate of not less than 90.

This paper will discuss the design of an asynchronous FIFO,Asynchronous FIFOs are widely used in the computer networking industry to receive data at a particular frequency and transmit them at another frequency. An asynchronous FIFO has two different clocks: one for read and one for write.-Asynchrinous FIFO design

一个很不错的误码率仿真介绍，看后会明白Matlab的误码率仿真原理！-A very good simulation of the BER introduced to understand after watching the bit error rate Matlab simulation principle!

我们自己创建各个的头部,系统只是把它们发送出去. 在实例中,由于我们要修改我们的源IP地址, 所以我们使用了setsockopt函数,如果我们只是修改TCP数据,那么IP数据一样也可以由系统来创建的. -To create all our own head, the system only to send them out. In the example, because we have to modify our source IP address, so we use the setsockopt function, if we just amend the TCP data, then the IP can also be from the same data system to create the.

串行通信接口标准经过使用和发展，目前已经有几种,但都是在RS-232标准的基础上经过改进而形成的.RS-323C标准是美国EIA(电子工业联合会）与BELL等公司一起开发的1969年公布的通信协议。它适合于数据传输速率在0～20000b/s范围内的通信。该文档是对RS232C标准的详解.-serial communication interface standards through the use and development of that there are already several, but they are in the RS-232 standard on the basis of improved form of. RS-323C standard of the United States EIA (Electronic Industry Association) BELL companies together in 1969 to develop the communication protocol. It is suitable for data transfer rate of 0 ~ 20000b/s within the scope of communication. The document on the understanding the standard RS232C.

在许多软件系统中，表格控件在对数据进行浏 览、编辑等操作方面都有良好表现。遗憾的是，Visual C++并没有提供直接支持表格操作的通用控制类。不 过，我们可以通过注册VisualC++5.O的ActiveX 控件中的Microsoft FlexGrid Control,version5.0 控件并添加到项目中来实现对表格的显示及操作。下 面将结合具体实例，介绍如何在对话框中加入表格控 件并实现对表格数据的显示、修改和保存。文中程序 是在中文WindowsNT4.0环境下，用VisualC++・5.0 编写的。 -In many software systems, forms control in the data view, edit and operational aspects such as good performance. Unfortunately, Visual C++ does not provide direct support to form a common operational control class. However, we can register VisualC++5. O The ActiveX controls in the Microsoft FlexGrid Control, version5.0 control and add to the project to achieve the right form of display and operation. Below with specific examples on how to add form controls in the dialog box and to achieve the display of tabular data, modify and save. This paper program is in the Chinese WindowsNT4.0 environment, using VisualC++ ・ 5.0 prepared.
