串口通讯实现文件传送，对vb下学习串口通讯有很好的借鉴-com file

DOS下的串口工具，用tc2就可以编译 内含CDT编排过滤 有问题请email 给我 ls99@far-china.com-an serial tool for DOS. Complied in turbo c 2.0,including CDT filter, email ls99@far-china.com if there is any question.

串口通讯程序,用vc写的很好的说明了用API涵数进行串口的读和写!- The string mouth communication procedure, very good showing which wrote with vc has contained the number with API to carry on the string mouth to read and to write!

CRC校验TS流文件的的PSI信息表，分析TS流文件的PAT表、PMT表、SDT表（注意项目文件中没有TS文件，要运行程序需要加入TS文件，并简单修改文件OPEN函数的参数）。-CRC Checksum TS stream file information table of the PSI, analysis TS stream file PAT table, PMT table, SDT table (note that the project document did not TS files, to run the program need to join the TS file, and modify the file a simple function of the parameters OPEN ).

GBSBEM(几何单反射椭圆模型)可以用来仿真功率－延迟－角度（pda-图）、功率延迟图、时间－角度的联合统计、波达方向的边缘特征和窄带衰落包络。适用于低层系统，包括微小区和微微小区、杂波绕射基站天线、发射机到接收机之间以及发射机和接收机的周围充斥着散射体的情形。由于其适用范围广泛且具有解析性质，揭示了空间无线信道不同特征间的相互联系，是进行研究的理想模型。-GBSBEM (geometric GBSBEM) simulation can be used to power-delay-angle (pda- Chart), power plans delayed, time-point joint statistics, DOA on the brink of decline and narrow envelope. Apply to the lower systems, including Microcell and Microcells, Clutter diffraction base station antenna, between the transmitter and receiver to the transmitter and receiver around the full scattering case. Because of its broad scope of application and analytic nature, Space Channel reveals the different features of the inter-linkages Research is the ideal model.

对原始的 ALOHA 协议的改进是"时隙 ALOHA"，介绍了离散的时隙，并增加最大的吞吐量。一个站可以发送只有初时隙和因而减少碰撞事故。在这种情况下，我们只需要对传输尝试 1 帧时间内不连续 2 帧-次，担心，因为在每个时隙期间只能发生碰撞。

一个小的试验，通过在vb环境下设置串口并发送和接收数据的小程序。-a small trial, in vb environment and set up serial transmit and receive data of small procedures.

用同步理论实现缓存通信：Producer发送0-200到Buffer，同时Buffer发送到Consumer-Cache implementation using synchronous communication theory: Producer Send 0-200 to Buffer, meanwhile Buffer sent to the Consumer
