是一个比较简单基础的socket(delphi)通信程序,供大家参考-is a relatively simple based on the socket (delphi) Communication Program, for your reference

principles of wireless communications

Delphi写的一个比较不错的 OPC DA Server程序，作为开发OPC Server的一个不错参考。OPC 是OLE在工控领域的应用，同一了不同组态软件之间及组态软件与应用程序之间的通讯标准，以前组态软件与应用程序之间的通讯主要是应用DDE技术。-Delphi wrote a quite good OPC DA Server procedures, the development of OPC Server as a good reference. OPC is OLE in the field of industrial applications, the same between different configuration software and configuration software applications and communications between the standard configuration prior to application software and communications between the main technology is the application of DDE.

mp3播放程序，视频部分功能-mp3 player, video some functions

"Hard to find" full description of ContactID protocol from Ademco used by many home security devices to send messages to CMS (Central Monitoring Station) about security events. Has full technical description and can be used to easy make CMS communication module that sends info from your alarm system to CMS station.

这个模拟器可以被用来衡量和情节网络容量性能和信号干扰比 （SIR） 性能的 LTE 网络与整数频率复用方案与重用因子 1 （IFR-1）。与重用因子 1 的频率复用方法意味着可用的频率资源使用的 LTE 网络中的所有单元格。级 LTE 由两个 Matlab 脚本文件 （LTE_main.m，LTE_configuration.m）、 三个 Matlab 函数文件 （LTE_IFR_sim_dist.m，LTE_IFR_sim_netwide.m，LTE_IFR_plot.m） 和一个 Matlab 垫文件 (bs_user_position.mat) 组成的系统。

vs2005开发环境下面用C#编写的虚拟RFID串口模拟器。当接从串口收到一个数据的时候，工具自动回复一个你定制的报文串。前提是需要有虚拟串口。也可以手动向串口发送报文的功能。-vs2005 development environment written in C# using the following virtual RFID serial simulator. Upon receiving a data received from the serial port when the tool automatically go back to a string of your custom message. The premise that the need for a virtual serial port. You can also manually send a message to the serial port function.

基于simulink的uwb仿真 uwb.mdl: UWB model - open this to begin. uwb_lib.mdl: Library blocks for UWB model. uwb_init.m: Initialization called before model is loaded. uwb_settings: Sets up structure containing system parameters ( uwb in workspace). uwb_imr.m: Initializes UWB channel impulse response. uwb_sv_*.m: Four M-files used to generate channel impulse responses (MAT files).-based on Simulink simulation of UWB uwb.mdl : UWB model-open this to begin. uwb_lib.mdl : Library blocks for UWB model. uwb_init.m : Initialization called before model is loaded. uwb_settings : Sets up structure containing system parameter s (UWB in workspace). uwb_imr.m : Initializes UWB channel impulse response. UWB _sv_*. m : Four M-files used to generate channel impulse r esponses (MAT files).
