This program simulates the minimization of a simple function with the multidirectional search method.

粒子滤波案例，结构有待改进,希望大家提点意见谢谢(the particle filtering method which needs to be modified by others)

比例积分型的GPC，由新的目标函数解出的控制率与常规PI控制有着一样的形式，这样就获得了一种具有PI结构的广义预测控制，而且其参数 、 有着明显的工程意义，整定原则基本类似于PID。(Proportional-integral-type GPC, the new objective function solution of the control rate with conventional PI control has the same form, so to obtain a PI structure with generalized predictive control, and its parameters, there is a clear sense of the project, setting basic principle is similar to PID.)

多种策略变权重系数的粒子群优化算法源代码，用于求解复杂函数极值问题。(Multiple strategies variable weight coefficient of particle swarm optimization algorithm source code, is used to solve complex function extremum problems.)

字典树的基本功能是用来查询某个单词（前缀）在所有单词中出现次数的一种数据结构，它的插入和查询复杂度都为O(len),Len为单词（前缀）长度，但是它的空间复杂度却非常高，如果字符集是26个字母，那每个节点的度就有26个，典型的以空间换时间结构。(The basic function of the dictionary tree data structure is used to query a number of times a word (prefix) appears in all the words, which insertion and query complexity are O (len), Len is a word (prefix) length, but its space complexity is very high, if the character set is 26 letters, and that the degree of each node will have 26, the typical structure of space for time.)

说明：  采用小波对信号分解和去噪。分解层数和使用的小波可以自己定义然后阈值去噪(Wavelet is used to decompose and denoise signals. The decomposition level and the use of wavelet can be defined by itself and then threshold denoising)

该程序为自编的一个关于模拟莱斯衰落信道的整个过程，包括信号的调制、经过莱斯信道和解调，最后经过计算误比特率得出莱斯信道的性能的好坏。(The program for the self-simulation of a Rician fading channel the entire process, including the signal modulation, channel, after Rice and demodulation, and finally calculated BER Rice come to channel the good and bad performance.)
