STBC_3x4_simulation

msk调制，以前作业时编的，很基本的东西，貌似还有dpsk(msk modulation operation for the past, and very basic things, looks like there dpsk)

用Matlab仿真的基于DRFM的等间隔直接转发干扰，内有时域和频域分析。(Matlab simulation with equal intervals based drfm forwarded directly interfere, sometimes within a domain and frequency domain analysis.)

基于QPSK和16QAM的OFDM仿真程序(OFDM simulation based on 16QAM and QPSK modulation)

基于Matlab的X-CT图像重建程序开发(Matlab-based X-CT image reconstruction program development)

基于压缩感知，利用最大似然函数进行DOA估计的两种方法(Based on compressed sensing, using the maximum likelihood function of the two methods for DOA Estimation)

These codes generate simulation results depicted in the paper titled J. Chen, H. Yin, L. Cottatellucci, and D. Gesbert, "Dual-regularized Feedback and Precoding for D2D Assisted MIMO Systems", IEEE Trans. Wireless Commun., 2017. Author: Junting CHEN Email: juntingc@usc.edu Date: May 20, 2016

外文资料里面的源代码，用平面波展开法计算二维声子晶体带隙,有小波分析的盲信号处理。( Foreign materials inside the source code, Computation Method D phononic bandgap plane wave, There Wavelet Analysis Blind Signal Processing.)

用一阶梯度法，共轭梯度法和变尺度法求解多变量的寻优问题，其中单变量的寻优用的是0。618法(One method used ladder, conjugate gradient method and the variable metric method for solving multi-variable optimization problems, single-variable optimization using the 0.618 Act)

一个二维的fdtdc++编写的程序，较完整，带有pml边界条件。感兴趣的可以下载看看。(A two-dimensional fdtdc++ preparation procedures, more complete, with pml boundary conditions. Interested can download to see.)

采用国际标准测试图lena进行测试。分别采用“基于等间隔采样的图像缩小”、“基于局部均值的图像缩小”两种方法进行图像缩小。并附有注释、程序清晰、易于阅读。相信图像初学者阅读后必定会有很大的收益。(jiyudengjiangecaiyangdetuxiangsuoxiao, jiyujubujunzhidetuxiangsuoxiao,)
