编程实现QPSK调制解调，计算其误码率；(QPSK modulation and demodulation programmed to calculate the bit error rate )

说明：  两个改进的EM算法，虽然比Matlab自带的运行速度慢，但更易理解算法的原理(Two improved EM algorithm, although more than Matlab s own slow, but easier to understand the principles of algorithm)

this matlab code is of interpolation of some given points using newton s divided difference method.

超级大电容以及电池的充放电仿真，根据功率控制从而得到给定的输出功率(Super capacitor and battery charge and discharge simulation, according to power control to get a given output power)

绘出DSB解调器的输出并给出功率为其0.001，0.01，0.05，0.1和0.3倍的白高斯噪声存在的情况下解调器的输出(Mapped DSB demodulator output and gives power to its 0.001,0.01,0.05,0.1 and 0.3 times the white Gaussian noise exist demodulator output)

利用matlab实现特征分解法music法的matlab程序实现，不是调用函数，而是通过算法思想一步步实现的，希望对完成课程作业的同学有用(Using matlab to achieve the characteristics of decomposition matlab program of law music law, not to call the function, but rather a step by step through the algorithm thought, I hope useful for students to complete coursework)

rs232收发程序matlab (rs232 transceiver procedures matlab)

连续Hopfield神经网络的优化—旅行商问题优化计算,在M ATLAB中完美运行(Optimization calculation of optimization and traveling salesman problem of continuous Hopfield neural networks, function perfectly in the M ATLABOptimization calculation of optimization and traveling salesman problem of continuous Hopfield neural networks, function perfectly in the M ATLAB)

公式法产生任意均值、方差和长度的高斯白噪声(Formula method produce any mean, variance and the length of the Gaussian white noise)

matlab学习书籍，很有用的，大家可以根据这个自学！(matlab learning books, very useful, we can according to the self-study!)
