A MATLAB solver for minimizing ||x||1 + p||Ax-b||2(A MATLAB solver for minimizing ||x||1+ p||Ax-b||2)

一个用于计算时间的界面，可根据需要进行修改(An interface for the computing time can be modified as needed)

brushlet结合c++一维信号变换，可以起参考作用(brushlet with c++ one-dimensional signal transformation)

基于AM DSB SSB调制解调的程序，较好的组织了语言描写，展示了通信系统中最基本的调制解调过程知识(Based the AM DSB SSB modulation demodulation process, preferably organized language description, showing a basic knowledge of the modulation and demodulation process in the communication system)

在3d不光滑曲面上的射线跟踪算法，效果比较好，希望可以帮助到大家(3d surface is not smooth in the ray-tracing algorithm, the effect is good, hope you can help to)

说明：  1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图 (1. Using Matlab generated sine wave, rectangular wave, as well as the white noise signal, and display their respective time-domain waveform of Figure 2. FFT to transform, showing their frequency spectrum, including sampling rate, frequency, data length of 3-on-demand. Made of the three signals in root-mean-square maps, power maps, as well as the number of root-mean-square map 4. Fourier Transform IFFT with the restoration of signals, and displays the sinusoidal signal the resumption of time-domain waveform)

用于matlab编程的入门文档，内含大量程序源码。(Getting Started document for matlab programming, containing a large program source code.)

说明：  用matlab来实现扩频通信仿真 很完整的仿真过程(Spread spectrum communication using matlab to achieve a very complete simulation of the process simulation)
