本书介绍的wcdma系统的基本原理：包括wcdma的系统结构，关键技术，数据传输基本技术，无线接口，基本信令流程，3G业务，实现等-The book described the basic principles of WCDMA systems: including WCDMA system architecture, key technologies, the basic data transmission technology, the wireless interface, the basic signaling flow, 3G business, realize, etc.

采用直接法实现实信号输出信道化发射机matlab仿真程序:可清楚地看出输入的基带信号被分别调制到了相应的频带上，并且输入的各路基带信号的频谱结构可以很明显地在输出的频谱中体现出来-Using the direct method to achieve real signal output channel of the transmitter matlab simulation program: You can clearly see that the input base-band signal is modulated separately to the corresponding frequency band, and the input signal spectrum with the roadbed structure can be clearly in the output reflected in the spectrum

LTE上行随机接入过程第一步，在PRACH上发送preamble信号，接收端接收并进行相关峰检测其延迟。该文档为条件1200km/h速度下，系统带宽20MHz，采样率30.72MHz的情况下，未考虑多普勒频移，小区半径为30km的前导检测过程。

读取Windows Mobile 6中的SIM卡存储信息，包括条目容量，已用条目数，存储长度等。C#编写，VS2005下编译。-Windows Mobile 6 to read the SIM card to store information, including entry capacity, has spent a few entries, storage length. C# Prepared, VS2005 compiler under.

基于labview的串口接收发送程序，使用查询方式-LabVIEW-based serial receiver to send a program, use the query

用S7-200PLC的自由口模式和VB中的MSComm控件方便地实现了计算机与S7-200（CPU224）PLC的通讯。计算机作为主站,用户通过计算机可以方便地设置房间的控制指令并向PLC发出控制或监测命令， PLC作为从站来响应计算机发送的指令并采取相应的动作并将房间的电、水、热信息发回到计算机。用户可以通过电脑屏幕实时地监视到房间的电、水、热信息并进行相应的处理。-with S7-200PLC the Free Port Mode and the VB MSComm to realize a trap Computer and S7-200 (CPU224) PLC communications. Computer as a master station, Computer users can easily set up control rooms PLC issued directives to control or monitoring orders, PLC as from the station to respond to orders sent by the computer and take corresponding action will be room for electricity, water, Heat fat information to the computer. The user can screen real-time surveillance of the room electricity, water and heat information and handled accordingly.
