PSNRandSNR

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is a space-time block coding based on the MIMO_OFDM communication system simulation design. This system consists of QPSK modulation and demodulation, IFFT modulation, space-time coding and decoding, based on training symbols such as communication channel estimation module.)

机械运动模拟， 凸轮机构绕中轴线旋转， 阻尼运动， 连杆机构的运动模拟， 凸轮的转动。 (Mechanical motion simulation, cam around the axis of rotation, damping motion, linkage of the motion simulation, the cam rotation.)

GM（1,1）动态模型预测源代码，可以预测未来老年人口的比重，较好的人口预测模型(GM (1,1) dynamic model to predict the source code, we can predict the future the proportion of the elderly population, the better the population forecasting model)

gui界面设计，通过简单的历程学会GUI，对于初学者很有帮助！(gui interface design, a simple course of Institute of the GUI, very helpful for beginners!)

小波变换中的同步挤压小波程序。支持GUI界面交互，也可独立运行，易改造，易结合。(The synchronous extrusion wavelet program in the wavelet transform. Support GUI interface interaction, also can run independently, easy to transform, easy to combine.)

SHIELDING EFFECTIVENESS OF DIFFERENT MATERIALS AT DIFFERENT FREQUENCY

用模最大值法提取小波脊，该例中又两条小波脊，所以是多脊提取。同时又施加惩罚函数，控制lamda的值，可以得到较为平滑的小波脊。( using maximum modulus extract wavelet ridge, the case has two wavelet ridge, it is a multi-ridge extraction. At the same time to impose the penalty function to control the value of lamda,the extracted ridge can be relatively smooth .)
