perbaikan terhadap STC untuk pergeseran15 dB

程序为常规AM，DSB，SSB调幅信号的调制与解调的MATLAB程序，其中单边带调制用两种方法进行调制：一种为频谱直接变换，另一种为希尔伯特变换实现(MATLAB for norm AM,DSB and SSB modulation and demodulation,besides,modulation for SSB,has tow ways:frequency spectrum transform and hilbert transform)

结合工程实例，介绍了利用大地测量法实现施工期边坡稳定性实时准动态监测的方法和仪器的使用情况。(Combined with engineering examples, this paper deals with the method of using land measurement during the realization of dynamic real-time accurate slope stability monitoring methods, and use of equipment.)

COMPARISON OF DIFFERENT MODULATION SCHEMES

主要用来计算非线性动力学中的混沌和分岔图像，即poincare图和分岔图、相图等(Mainly used to calculate the nonlinear dynamics of chaos and bifurcation images, namely Poincare diagram and bifurcation diagram, phase diagram and so on)

软件调试方面的书籍，内容不错，而且只有100多页，便于学习，感觉还不错，与大家共同分享。(Software debugging of books, the content is true, and only 100 pages, easy to learn, feel pretty good, and everyone shared.)

GNU dsp模拟器，运行在Linux上，主要支持对TMS320C54X型号dsp的模拟。用matlab和c写成(Gnu Digital Signal Processor Simulator. The goal is to develop a DSP Simulator for Linux. The firstchip supported will be the TMS320C54x.)

是通信原理的PCM编码过程，采用均匀量化(The communication principles of PCM encoding process, using uniform quantization)

说明：  16QAM的数字通信系统的仿真，包括调制解调，上下变频，加入了高斯白噪声，并且每个步骤都生成相应的图形(16QAM digital communication system simulation, including the modulation and demodulation, frequency conversion from top to bottom, by adding a Gaussian white noise, and each step to generate the corresponding graphics)
