摘要-Impulsive噪音缓解了正交频分复用（OFDM）可以使用两个阈值剪贴归零方案来完成。我们引入一个新的结合脉冲噪声消除方法，称为clippingreplacement-归零计划，其中有三个考虑阈值：限幅阈Tclip，更换门槛TREP和归零门槛Tnull。当接收到的OFDM样本的幅度高于TREP和下方Tnull我们将其设置为所述平均幅度JX？无噪声的OFDM样本第j。模拟结果表明，附加的动作，替换动作，与TREP的一个很好的选择带来在误码率的降低。

TCP/IP协议是一个比较复杂的协议集，有很多专业书籍介绍。在此，我仅介绍其与编程密切相关的部分：以太网上TCP/IP协议的分层结构及其报文格式。-TCP/IP protocol is a more complex set of agreements, there are many professional books introduced. Here, I just introduced its programming and closely related to the part : Ethernet TCP/IP protocol to the hierarchical structure and its message format.

程序给出了CAN总线接口的通讯的MATLAB仿真代码,希望能给大家提供帮助.-procedures given CAN Bus Interface communications MATLAB simulation code, hope you can help.

何在Visual C++开发平台下,利用MATLAB 数学库和图形库开发脱离MATLAB环境独立运行的应用程序的方法,通过一个实例给出了混合编程的详细步骤。该方法应用可有效地提高软件开发的高效性和可靠性。-What is Visual C++ Development platform, using the MATLAB mathematical library and graphics library from the MATLAB environment to develop applications that run independently of the method, an example is given of the detailed steps of mixed programming. Application of the method can effectively improve software development efficiency and reliability.
