说明：  经典无线链路预算模型，预测了在自由空间中由地形的非规则性造成的中值传输衰落。该模型适用于频段为20MHz至40GHz、路径长度为1km至2000km的情况。对于给定的传输路径，该计算机程序通过频率、路径长度、极化方向、天线高度、表面绕射率、地面有效半径和地面导电常数等参数可以确定传输损耗的大小。(Classic wireless link budget model, forecasts the in free space caused by terrain of regularity in the value decline.The model is suitable for the frequency of 20 MHZ to 40 GHZ, path length of 1 km to 2000 km.For a given transmission path, this a computer program can calculate the value of the transmission loss by frequency, path length, polarization direction, antenna height, surface diffraction, effective radius of the ground and ground conductivity constant parameters and so on.)

说明：  实现对稀疏信号的恢复，完成对稀疏信号的重建，压缩感知算法(siganl reconstructed)

封装了windows操作串口的几个API（CreateFile， ReadFile，WriteFile，SetComState）。串口的读写设置这几个操作都可以简单地只用关键一两个参数就能实现操作。也是一个很好的例子，我写这个之前查了不少资料，感觉非常麻烦，索性发出来给新手们作个样例(Windows serial COM port access class，it includes CreateFile, SetComState，ReadFile，WriteFile，CloseFile)

这是一个去极值滑动窗口数字滤波器算法，在ADC采样的时候可以用这个算法去除脉冲干扰。(This is digital filter algorithm which removes extreme value，and it works just like a sliding window, we can use this algorithm to remove glitches in ADC sampling。)

适合系统学习OFDM技术,本文设计并实现OFDM通信系统的调制,解调部分的数字电路,采用实验板或自行设计电路进行调试,并采()

说明：  产生数字基带信号，加入AWGN高斯白噪声在信道中传输，检测出原始基带信号，并绘制理论和仿真误码率曲线(The digital baseband signal is generated and transmitted in the channel with AWGN white Gaussian noise. The original baseband signal is detected and the theoretical and simulation BER curves are drawn)
