DataCollectSystem-ForVS008

实现串口通信 可以收发数据 可以是数字也可以是ASCII(Serial communication)

分析了 IEEE 802.15.4a的信道模型，并分析了现今测距的方法：CHAN与TAYLOR等，并在此基础上做了改进(Analysised the channel of IEEE 802.15.4a,and analysised some methods for TDOA and TOA . )

实现了VB6下的通讯API的封装 实现了VB6下的通讯API的封装 实现了VB6下的通讯API的封装 实现了VB6下的通讯API的封装(实现了VB6下的通讯API的封装 实现了VB6下的通讯API的封装)

DSDV协议在ns2中的实现，可以直接使用，无需调试(DSDV protocol implementation in ns2, can be used directly, without debugging)

本程序是将串口实时接收到的数据，然后将数据进行曲线绘制。(The data received by serial port is plotted in real time.)

光源布局优化蒙特卡洛算法仿真等等对于平面估计定位精度提高(Simulation of light source layout optimization Monte Carlo algorithm and so on for improving the accuracy of plane estimation)

本论文以OFDM系统为基础，介绍了OFDM系统的基本原理，以及使用OFDM技术的优势所在，并且展望了今后的无线移动技术的发展前景。在简单介绍OFDM原理的同时，着重阐述了OFDM系统在不同信道环境和不不同实现方式下的误码性能。主要包括了OFDM系统在加性白高斯信道，在加性白高斯信道和多径干扰两种不同信道环境下系统的误码性能，其中后者还研究了系统在有保护间隔与无保护间隔的误码性能比较。在理论分析的基础 (This thesis is based on the OFDM system, the basic principle of the OFDM system, as well as the advantages of using OFDM technology, and future prospects for the development of future wireless and mobile technologies. OFDM principle in brief, focusing on the BER performance of OFDM systems under different channel conditions and different implementations. Including OFDM system in additive white Gaussian channel, additive white Gaussian channel and multipath interference of two different channel environment, the system BER performance, the latter of which also studied the system in a protected interval without guard interval BER performance comparison. The basis of theoretical analysis)

不错的客户端连接程序，希望大家喜欢，里面是一个客户端的程序，一会会提供服务端的程序(good client procedures in the hope that everyone likes, there is a client process, will provide a service side of the process)

高通，rex，OS，很好的文档~~~！！！(Qualcomm, rex, OS, a very good document ~ ~ ~)

数字通信技术的收集与介绍 希望对大家有用( Communicate)
