使用FR共轭梯度法求解无约束问题 输入包括初始点，目标函数和梯度 输出包括最优点和最优解，还有迭代次数(Use FR conjugate gradient method for solving unconstrained problems including initial entry points, the objective function and the gradient of the output, including the advantages and the most optimal solution, as well as the number of iterations)

BPSK与QPSK调制解调系统的Matlab仿真程序； 发送滤波器与接收滤波器均为根升余弦滚降滤波器； 信道噪声为加性高斯白噪声； 绘制BPSK与QPSK调制下的误码率与信噪比曲线图，并与理论曲线进行对比。 (BPSK and QPSK modulation and demodulation systems Matlab simulation program transmit and receive filters are root raised cosine filter roll-off filter channel noise is additive white Gaussian noise draw BER BPSK and QPSK modulation with a letter under noise ratio graph and compare with the theoretical curve.)

近似熵m文件 保证正确运行 绝不骗人(ApEn m file to ensure correct operation will not lie)

说明：  这是MATLAB软件中的产生高斯白噪声的函数，通过参数设置得到你所需要的白噪声，同时可以用于研究随机信号产生的方法。(This is the MATLAB software have a function of Gaussian white noise, through the parameters you need to be white noise, at the same time can be used to study the methods of random signal generator.)
