这是根据点拟合圆和直线的matlab程序，比较简单实用(This is the basis of points won and a straight line fitting the matlab procedure is relatively simple and practical)

vc2008 dos 程序 已知AB两点坐标，半径R。 求2个圆心。 公式使用MATLAb推导的，做了一点简化，和小的改动。 都在函数 double jisuanYanxin(double Ax,double Ay,double Bx,double By,double R) 里面(vc2008 dos program known AB two coordinates, radius R. Seeking two center of the circle. Formula derived using MATLAb do a little simplification, and small changes. In the function double jisuanYanxin (double Ax, double Ay, double Bx, double By, double R) which)

Reed-Solomon信道编解码代码，解决底层通信问题(Reed-Solomon code and encode)

LTE下行链路空分复用开环。仿真配置：16QAM调制、1/3码率Turbo编码、10MHz带宽、每个子帧一个PDCCH符号、单码字，8次迭代Turbo译码、早期终止机制、MMSE（最小均方误差）MIMO接收器，PDSCH发射端进行空分复用预编码。信道模型是LTE-MIMO信道附加AWGN信道。(LTE downlink space division multiplexing ring opening. Simulation Configuration: 16QAM modulation, 1/3 rate Turbo code, 10MHz of bandwidth, one PDCCH per subframe symbol, single code word, 8 Turbo decoding iterations, early termination mechanisms, the MMSE (minimum mean square error) the MIMO receivers, PDSCH transmitting terminal space division multiplexing precoding. Channel model is LTE-MIMO channel additional AWGN.)

Z=X+Y 求Z的分布 並且畫出圖 並與理論公式值做比較 (Z = X+ Y seeking to draw the map the distribution of Z and compare with the theoretical formula for the value)

函数功能是基于二进制编码遗传算法的PID整定(Function function is based on the binary-coded genetic algorithms for PID tuning)

计算数独的好方法，能够快速解决问题，使用方便(Good way to calculate the number of independent, able to quickly solve the problem, easy to use)
