数字图像处理project4， 人脸检测，利用matlab自带工具箱(Digital image processing project4, face detection, built using matlab toolbox)

结构动力学中Newmark方法编写的结构振动计算程序，希望对有需要的同志有帮助(a small programe about Newmark applied to structural vibration)

LTE下行链路空分复用闭环。仿真配置：16QAM调制、1/3码率Turbo编码、10MHz带宽、每个子帧一个PDCCH符号、单码字，8次迭代Turbo译码、早期终止机制、MMSE（最小均方误差）MIMO接收器，PDSCH发射端进行空分复用预编码。信道模型是LTE-MIMO信道附加AWGN信道。(LTE downlink closed loop space division multiplexing. Simulation Configuration: 16QAM modulation, 1/3 rate Turbo code, 10MHz of bandwidth, one PDCCH per subframe symbol, single code word, 8 Turbo decoding iterations, early termination mechanisms, the MMSE (minimum mean square error) the MIMO receivers, PDSCH transmitting terminal space division multiplexing precoding. Channel model is LTE-MIMO channel additional AWGN.)

亲测可用的EMD分析，直接调用改函数即可。具体可看代码说明部分，或者在matlab里help emd(EMD analysis of pro-test available, direct call function can be changed. Specific instructions can look at the code section, or help emd in matlab in)
