Truss-FEM

这个是matlab下时频分析中之非平稳信号的一般处理的全部代码(under Matlab is the time-frequency analysis of non-stationary signals in general will deal with all the code)

用MATLAB对OFDM系统进行了仿真分析。包括信道调制方式16QAM、快速傅立叶变换、循环前后缀及信道函数窗函数等，最后计算了系统的误码率，毕设资料，非常珍贵。( MATLAB OFDM system for the simulation. the simulation uses OFDM each function module, Including 16 channel modulation QAM, Fast Fourier Transform, revolving around prefix and channel Function window function, etc. Finally, Calculate BER for OFDM system)

说明：  一种基于动态路径损耗指数的最小能耗中继路由 (Dynamic Minimum Energy Relay Routing，DMERR）算法，该算法能够获取巷道内各处准确的路径损耗指数，准确计算巷道内每处的最佳通讯距离，从而节省通信能量。(the Minimum Energy Relay Routing (DMERR) algorithm which is based on dynamic path loss parameter is proposed, this algorithm can save the energy of communication by obtain the exact path loss parameter of each place in roadways and calculation the optimum communication distance accurately. )

3. Setting of a suitable threshold value.Then apply wavelet de-noising and compression on wavelet coefficients and thresohlding using global positive threshold value. So that a compressed image can be transmitted in an efficient manner.

通过不同的方式演示混沌系统，产生不同的混沌序列。(Chaotic system is demonstrated in different ways, and different chaotic sequences are generated.)

说明：  蒙特卡洛简单示例，适合初学者，简单容易，吐血整理(Monte Carlo simple example, suitable for beginners, simple and easy, vomiting blood)
