QPSK调制与解调，并有误码率的分析，加了 信道噪声。(QPSK modulation and demodulation, and bit error rate analysis, the addition of channel noise.)

实现输入一串数字，然后matlab可以将数字对应的蜂鸣音播放出来（类似于电话的拨号）(Achieve input a string of numbers, then you can figure corresponding matlab beep play out (similar to dial-up phone))

Title: "Modeling Lung Cancer Diagnosis Using Bayesian Network Inference" This demo illustrates a simple Bayesian Network example for exact probabilistic inference using Pearl s message-passing algorithm. Introduction: Bayesian networks (or belief networks) are probabilistic graphical models representing a set of variables and their dependencies. The graphical nature of Bayesian networks and the ability of describing uncertainty of complex relationships in a compact manner provide a method for modelling almost any type of data.

ofdm仿真模型,该文件可实现ofdm通信系统的Simulink仿真，对ofdm通信系统有个清晰的理解(ofdm simulation model)

Matlab遗传算法整理，涉及GA算法。(Sorting out genetic algorithm.matlab.)

matlab中fsolve语句数值效果较好，采用的解法是将方程组转化为最小二乘问题，调用指令lsqnonlin求解，所以，它参数的选取和优化指令的用法是一致的(matlab numerical results in fsolve statement better solution is to use the equations into a least squares problem, call the command lsqnonlin solution, therefore, it is parameter selection and optimization of instruction is consistent with the usage of)
