模拟空间多孔介质,用matlab三维曲面重构。(The porous media in the space is simulated, and the three-dimensional surface is reconstructed.)

这是一份低轨道卫星建模的资料，比较简洁适合学习(This is a low-orbit satellite modelling data, relatively simple and suitable for learning, recommend to see)

模拟调制识别各特征参数随信噪比变化曲线。信号的瞬时信息包括瞬时幅度、瞬时相位、瞬时频率及其不同角度的统计特征值，其中瞬时幅度、瞬时相位、瞬时频率是一个信号最基本的特征。（AM、DSB、SSB、VSB、FM、AM-FM）(Simulated Modulation Recognition Curve of Variation of Characteristic Parameters with Signal-to-Noise Ratio)

说明：  对输入信号进行量化，n为你想要的量化级数；可输出量化前后信噪比，量化后信号，和量化后的二进制序列(Quantize the input signal, n is the quantizing series you want; output the signal-to-noise ratio before and after quantizing, the quantized signal, and the quantized binary sequence)

关于常规信号，线性调频信号和相位编码信号的检测和估计(detection and analaysis of normal signal, LFM and phase coding signal.)

OPTICAL COMMUNICATIONS MATLAB calls OptiSystem CO-OFDM.

该程序能够较好的仿真出Missive MIMO系统下 信道估计的误码率，及还 有部分的MSE代码，可以供大家参考一下！(This program can better simulate the error rate of channel estimation under Missive MIMO system, and also There are some MSE code that you can refer to!)

说明：  DL/T860系列文档完整版，IEC61850通讯模型(DL / T860 series document complete version, IEC61850 communication model)

计算矩形栅格或三角栅格阵列天线栅瓣图，优化天线单元间距设计(caculate grating lobes of rectangular grid or triangular grid array)

实现使用music算法进行频率估计，并绘图(Achieve the use of music algorithm for frequency estimation, and graphics)
