这是一个用于油田电表抄表的程序；能够发送手机短信，使用SQLSERVER数据库储存数据；使用pcomm通讯控件控制无线调制解调器，调用AT指令集。正在现场运行，极有应用价值。-This is a meter used for oil field meter reading procedures capable of delivering a phone message, using a database storing data SQLSERVER PComm communications control to control the use of wireless modems, call the AT instruction set. Were at the scene running, there is a strong application value.

基于bpsk的直接序列扩频源码，实现效果不错-BPSK-DSSS

想做AVR下移植UC／OS－II RTOS的朋友可以用这个教程来摆脱ICC编译器的单调界面，使写程序与改程序变得更加简单，方便-AVR wants to transplant under the UC/OS-II RTOS of a friend can use this course to shake off the monotony of ICC compiler interface, so that written procedures and the procedures to become more simple and convenient! ! !

CBS（小区广播）程序实现手稿，在Motorola源程序上修改，现已商用，比较经典-CBS (Cell Broadcast) program manuscripts, modify the source code in Motorola, is now commercial, more classical

1)生成2KHz和8KHz的混合信号，使该信号通过上述滤波器，观察滤波前后的波形变化和频谱分布情况。 2) 在改信号中加入高斯白噪声，观察滤波前后的波形变化和频谱分布情况3) 将上述滤波器改为中心频率为100KHz的带通滤波器，信号源为带外的90KHz和带内的100KHz的混合正弦信号，。 4) 用M文件实现上述低通滤波器。 -1) 2KHz and 8KHz to generate the mixed-signal, so that the signal through the above-mentioned filter, filter before and after observation of the waveform and spectrum distribution of the changes. 2) add to the signal in white Gaussian noise was observed before and after filtering and spectral waveform changes in the distribution of 3) will be replaced by the above-mentioned filter center frequency of 100KHz band pass filter, the signal source for the band and the band of 90KHz 100KHz Sine of the mixed signals. 4) achieve the above-mentioned documents with M low-pass filter.
