短信群发系统，在一些业务范围广泛的公司中，当公司有了新的通知要告诉在外地的员工，通常使用拨打电话的方式，这样虽然能把事情说清楚，但是当在外的员工比较多时，工作量很大，为了解决这个问题，可以开发一个企业短信群发管理系统。企业短信群发管理系统主要利用硬件短信猫发送短信，并且可以查看SIM卡中收到的短信。(Mass messaging system, in a number of business a wide range of companies, when the company has a new notification to tell the staff in the field, normally used by calling the way, so although things can make it clear, but when the staff out for a long time compared , the heavy workload, in order to resolve this problem, can develop an enterprise management system for mass text messaging. Short Message management system for enterprises mainly use the hardware to send SMS text messages a cat and can view the SIM card text messages received.)

音频信号通过LM386放大，包括四元数的各种计算,D-S证据理论数据融合。( LM386 audio signal amplification, Including quaternion various calculations, D-S evidence theory data fusion.)

LDPC校验矩阵生成、高斯消去法编码、BP译码程序，可以作为自己编写LDPC编译码程序的参考。因为matlab代码效率不高，所以这个程序仿真起来比较慢.(LDPC check matrix generation, Gaussian elimination coding, BP decoding procedure can be used as its own procedures for the preparation of LDPC codec reference. Because matlab code efficiency is not high, so this process is relatively slow simulation together.)

语音信号处理的fft算法 编程实现了FFT算法，运用编写的FFT程序对信号进行FFT计算和还原，待分析的信号是一段音乐，与Matlab的FFT函数进行了比较并设计系统页面 (FFT algorithm for speech signal processing FFT programming algorithm, the use of the preparation of the FFT program to calculate and restore the signal FFT, the signal to be analyzed is a piece of music, and the Matlab function of the FFT and the design of the system page)
