LS法信道估计

说明：  如题，产生线性调频信号及通过匹配滤波处理(The linear frequency modulation signal is generated and processed by matched filtering)

数字通信中的16QAM映射，采用格雷码编码，包括星座图的显示，简单明了清晰，由此可以退出64,128QAM的matlab编码(Digital communication 16QAM mapping, the use of Gray coding, including the constellation display, simple clear, it can be out of the 64,128 QAM matlab code)

在VC++6.0中用MSComm控件编程，可以实现串口接(used in VC 6.0 MSComm programming, serial port access can be achieved)

说明：  QT编写的CAN通讯源代码文件，通讯盒子用的是珠海芯创的can盒(The source code file of CAN communication written by QT. The communication box is the can box of Zhuhai Xinchuang.)

PuTTY是一个Telnet、SSH、rlogin、纯TCP以及串行接口连接软件。较早的版本仅支持Windows平台，在最近的版本中开始支持各类Unix平台，并打算移植至Mac OS X上。除了官方版本外，有许多第三方的团体或个人将PuTTY移植到其他平台上，像是以Symbian为基础的移动电话。PuTTY为一开放源代码软件，主要由Simon Tatham维护，使用MIT licence授权。随着Linux在服务器端应用的普及，Linux系统管理越来越依赖于远程。在各种远程登录工具中，Putty是出色的工具之一。Putty是一个免费的、Windows x86平台下的Telnet、SSH和rlogin客户端，但是功能丝毫不逊色于商业的Telnet类工具。目前最新的版本为 0.68 latest release(PuTTY is a Telnet, SSH, rlogin, pure TCP, and serial interface connection software. The earlier version supported only the Windows platform, and in recent versions began to support various Unix platforms and was intended to be ported to Mac OS X. In addition to the official version, there are many third party groups or individuals that migrate PuTTY to other platforms, such as Symbian based mobile phones. PuTTY is an open source software that is maintained primarily by Simon Tatham and licensed using the MIT licence. With the popularity of Linux applications on the server side, Linux system management is becoming more and more dependent on remote. Putty is an excellent tool for various remote login tools. Putty is a free, Telnet, SSH, Telnet, and rlogin client on the Windows X86 platform, but it is no less functional than the business class tools. The latest version is 0.68 latest release)

说明：  基函数扩展模型相关matlab代码，包含信道估计及其均衡 。(The basis function extends the model related matlab code, including channel estimation and its equalization.)

这个matlab代码仿真了M-QAM的传输。M的取值不同，调制方式分别为4QAM，16QAM，64QAM等。传输信道为AWGN信道，能出误码率曲线。(The matlab code simulation of the M-QAM transmission. The value of M, the modulation mode of 4QAM, 16QAM, 64QAM. The transmission channel is AWGN, the BER curves.)

实现各种MIMO检测算法，包括MRC，ZF，MMSE和SIC(Implementation of MIMO Detection Algorithms)

Modbus4J源代码，方便大家查看具体的协议内容(Modbus4J.rar is a file that describes how control the PLC by Java language)

说明：  该资源为应用GNUradio工具，对USRP的开发，主要实现了频谱感知，以及根据频谱感知的结果进行ofdm通信的功能(This resource is the development of USRP using gnuradio tool. It mainly realizes the function of spectrum sensing and OFDM communication according to the result of spectrum sensing)
