已知光纤各参数，纤芯、包层折射率，芯径以及传输波长，做出光纤特征方程随U值变化的曲线，可据此求出U，继而求出传输常数(get the propagation constant by solving the characteristic function in a multimode fiber)

经典的瑞利衰落信道仿真模型-jakes模型。程序可以修改不同的入射路径个数。仿真结果是不同入射路径个数的jakes模型和同分布的瑞利衰落的包络分布对比。直接运行“tu.m”(The classic Rayleigh fading channel simulation model-jakes model. Program can modify the number of incident path. The simulation results compare jakes model of different incident paths with distribution of Rayleigh fading.)

波动方程正演模拟，交错网格二阶和四阶，和规则网格。适合新手学习。(Wave equation forward modeling, suitable for beginners to learn.)

说明：  优秀的ansys ；matlab计算；分析；混凝土开裂计算(Excellent ansys; matlab calculation; analysis; concrete cracking calculation)

说明：  Today’s wireless networks are characterized by a fi xed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15 to 85 with a high variance in time. The limited available spectrum and the ineffi ciency in the spectrum usage neces- sitate a new communication paradigm to exploit the existing wireless spectrum opportunistically

说明：  自己写的Canny算子的matlab实现和演示。程序虽然不大，但相信也能给大家一些参考。 (himself wrote the Canny Operator Matlab realization and demonstration. Procedures not much, but I believe that can give you some information.)

这是求导波中lamb波频散方程很好的MATLAB代码 绝对好用(To solve the dispersion curve of lamb wave by use of MATLAB program)

Quantum Particle Swarm Optimization matlab

说明：  matlab源程序 包含图像处理 OFDM的系统性能(matlab source code contains the OFDM system performance image processing)

可以实现对大量数据的实时在线预测及其分类效果(The real-time online prediction and classification effect of a large number of data can be realized)
