实现了CS8900的驱动-Realize CS8900 driver............

作为通信手段的蜂窝电话，除了它用于语音通信，还它用于发送消息的 SMS的名称的文本。高度数字犯罪声称多分层安全制度的存在。一门安全系统，一般应用于具体的住房，通常称为门。所以这门的访问必须要醒的。错过了呼叫服务和 SMS 的可以作为数据通信系统介质，利用 GSM 蜂窝网络稍后作为返程要打开/关闭大门，与作为控制器系统的计算机。所有手机号码有访问控制那里的门计算机数据库中的。

This is an algorithm for DynamicChannel Allocation in GSM frequency planning. The source code is being developed and will be uploaded soon.

stm32 can总线收与发 把数据写到两块stm32单片机里面 然后然后实现can收与发  并且通过usart1转送到电脑

c语言写的通讯方面的源代码，有一定参考价值，是从其它站点下载的。-c language written communications source code and a certain reference value is downloaded from the other site.

In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.-In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.
