关于OFDM的matlab仿真，调制、解调以及误码分析(On the OFDM simulation, modulation and demodulation error analysis)

说明：  这是关于matlab图行处理方面的源代码，说明matlab有强大的图形处理功能(This is a matlab figure on the source code line treatment, indicating that matlab has powerful graphics capabilities)

大学物理实验 基于matlab的光学实验仿真(College physics experiment based on the optical experiment simulation matlab)

给出比较少见的16PSK的仿真算法，包括高斯信道，瑞利信道及线性时不变信道。其中，在瑞利信道中，给出了均衡前均衡后比较结果，从中可以看出均衡的效果(is relatively rare in the estimation algorithm, including Gaussian Channel, Rayleigh channel and the linear time-invariant channel. Of these, the Rayleigh Channel, is a balanced balanced ago after the results of the comparison, from which one can see the effect of balance)

Calculate actual distance between two points on Earth, given their Lat Lon Alt, in Km

这个是用MATLAB程序编写的回波消除的代码，效果不错，简单明了(This is a MATLAB programming with the echo cancellation code, the effect is good, simple and clear)
