time series prediction use ANN

说明：  matlab下的数字信号处理实例 当工具书用也不错(under matlab examples of digital signal processing tool when used well)

具有完全识别车牌的matlab源代码，执行效率高！(With full recognition of vehicle license plate matlab source code, high efficiency.)

说明：  多目标规划的概念是 1961年由美国数学家查尔斯和库柏首先提出的。多目标最优化思想，最早是在1896年由法国经济学家V.帕雷托提出来的。他从政治经济学的角度考虑把本质上是不可比较的许多目标化成单个目标的最优化问题(The concept of multiobjective programming was first proposed by Charles and Cooper, American mathematicians, in 1961. The idea of multi-objective optimization was first put forward by the French economist v. Pareto in 1896. From the perspective of political economy, he turned many objectives that are essentially incomparable into optimization problems of a single objective)

ALOHA协议的思想很简单，只要用户有数据要发送，就尽管让他们发送。当然，这样会产生冲突从而造成帧的破坏。但是，由于广播信道具有反馈性，因此发送方可以在发送数据的过程中进行冲突检测，将接收到的数据与缓冲区的数据进行比较，就可以知道数据帧是否遭到破坏。(ALOHA protocol s thought is very simple, as long as the user data to be sent, although let they send. There are, of course, such conflicts which cause the destruction of the frame. But, because the radio channel has feedback, so the sender can be tested to the conflict in the process of sending data, the received data comparison with data of the buffer, you can know whether data frame was damaged.)

计算互信息非常有用的一组程序,是小学期课程设计的题目，FIR 底通和带通滤波器和IIR 底通和带通滤波器。( Mutual information is useful to calculate a set of procedures, Is the topic of the elementary school stage curriculum design, Bottom-pass and band-pass FIR and IIR filter bottom pass and band-pass filter.)

说明：  经典的石子划分问题，不同质量和数量的石子进行划分，以求最优解(Classic stone division, different quality and quantity of stones to be divided, with a view to the optimal solution)

MPSK_QAM，MPASK下的QAM调制方式，供参考(MPSK_QAM, QAM modulation MPASK under reference)

实现不同噪声情况下qpsk的调制，并得出了星座图。(Implement different noise situation of QPSK modulation and the constellation diagram is obtained. )
