nec9234串口调试程序，主要用于9234的串口应用

扩频发射机，信道编码采用(2, 1, 7)卷积 码, 扩频模块采用扩频长度255 的kasami码, 极性变换模块为3bit 量化模式, 内插模块为每两比特间插入7bit 和输出滤波为16 阶的FIR 滤波器。-direct sequence spread spectrum transmitter

串口调试源代码，自己动手已经实现，能够完成与单片机的串口通信-serial debug source code, has achieved its own hands, and MCU to complete the serial communications

基于Matlab，采用判决反馈均衡器对信号进行均衡的仿真程序-Based on Matlab, the use of decision feedback equalizer for the signal-balanced simulation program

对各种手机进行编程的工具包源码gsmlib 1.9版本。--Gsmlib 1.9 tool packet codes which can be used to program many kinds of mobilephone.

手机图纸设计用的- The handset blueprint design uses

关于串口通信的，用C++编写的代码，能够实现相关设备和计算机的通信，比如实现三维罗盘和计算机的通信，可以获得三个角度值

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.
