说明：  圆拟合，通过已知的多组数据，拟合出最小误差的圆(Given a set of measured x,y pairs that a re supposed to reside on a circle, but with some added noise. A circle to these points, i.e. find xc,yc,R, such that (x-xc)^2+(y-yc)^2=R^2)

由于硬判决在判决过程中将接收直接判决为[1 0],而损失了相应的近似信息，导致了接收信息在某种意义上的浪费。软判决将接收电平量化，尽可能保存相应的信息，故可以提高译码性能。(soft descision decoding)

matlab交叉验证cross Validation，把样本集分为训练集和测试集，防止网络出现过拟合，提高网络的泛化能力和预测精度(cross Validation for matlab，to estimate the test accuracy,training accuray and validation accuracy of a neural network)

here is the code for makemcode in matlab

风力发电机部件及模型，包括风力发电机的变流器、发电机、以及并网部分(Wind turbine components and models, including the part of the wind turbine inverters, generators, and grid)

给出了simulation and software radio一书的QPSK,OFDM章节中的源代码，并全部经过编译运行，结果正确可靠(Simulation and software radio book QPSK OFDM sections of source code, and all compiled to run accurate and reliable results)

matlab实现D2D链路仿真 对小区中的D2D链路进行单工双工划分，并计算链路长度。改变链路距离和发射功率，研究链路分组情况(Matlab implementation of D2D link simulation Simplex duplex division of the D2D link in the cell, and calculate the length of the link. Link distance and transmit power are changed, and link grouping is studied)
