用API函数集写串口通信程序

华为ＧＳＭ模块的测试程序，其中包括拨打电话，接听电话以及来电显示等功能，适合学习ＧＰＲＳ入门-Huawei GSM module test procedures, including call, receive calls, as well as features such as caller ID for learning GPRS portal

图象采集的算法包含图象速率及采集的计算公式和抽样原理的技术文档-Image acquisition rate of the algorithm contains the images and the formula for calculating the collection and sampling principle technical documentation

Assembly AVR to test RS232 serial communication

这是关于数字通信的一些程序,希望对大家有所帮助-This is the digital communication on some of the procedures, we hope to help

vc++ 演示搜索本地可用串口，把本机上可以使用的串口号都列出来，在下拉窗口中可选，本程序是双串口互相通讯，测试串口设备，未完成主要功能。只完成了串口搜索

这是我收集的几个通信基础理论的Matlab仿真实现，包括bpsk、qpsk、ofdm以及信号衰减和延迟的仿真。尽管不是我本人原创，但比较都经典。-This is my collection of several communications infrastructure theory Matlab Simulation, including BPSK. QPSK, and the OFDM signal attenuation and delay in the simulation. Although it was not my original, but more are classics.
