本例用matlab语言实现了4QPSK的编解码及通过awgn信道的仿真。采用蒙特卡罗仿真法，得到误码性能，绘制曲线。可用于算法研究或课程学习。(Matlab language used in this case achieved 4QPSK codec and channel through awgn simulation. Monte Carlo simulation method, the BER performance, drawing curves. Algorithm can be used for research or courses.)

说明：  数值分析的m文件，包括一阶 二阶导数的三点 五点公式，中点公式等(Numerical Analysis of m documents, including a second order derivative of the 3 5 point formula, midpoint formula, etc.)

该工具箱的目的是要帮助人们理解计算机视觉方法引用另一种为在 matlab 的源代码。 因此，一些方法被 re-implemented，即使当其源代码不可用时，matlab 最初，具有方法。 例如 re-implemented kmeans 算法。(The aim of this toolbox is to present source codes in matlab as another kind of references for helping people to understand computer vision methods. Thus, some methods were re-implemented, even if matlab has the methods originally, when their source codes are not available. For example, kmeans algorithm was re-implemented. Howerver, notice that the built-in functions are faster than functions created in this toolbox because the built-in functions are mostly written in C. )

说明：  该程序计算了2*2的MIMO信道在瑞利衰落下、BPSK调制下迫零均衡的误比特率，并有理论值和仿真值的对比(The program calculates the bit error rate of 2* 2 MIMO channel in Rayleigh fading, BPSK modulation, the zero forcing equalizer, and a comparison of the theoretical values ​ ​ and simulation values)

粒子滤波matlab仿真程序.粒子滤波的基本思想是：首先依据系统状态向量的经验条件分布，在状态空间抽样产生一组随机样本集合，这些样本集合称为粒子；然后根据观测值不断调整粒子的权重大小和样本位置；最后通过调整后的粒子信息修正最初的的经验条件分布，估计出系统状态和参数。该算法是一种递推滤波算法，可以用来估计任意非线性非高斯随机系统的状态和参数。 粒子滤波主要有三步基本操作：采样（从不含观察值的状态空间产生新的粒子）、权值计算（根据观察值计算各个粒子的权值）、重采样（抛弃权值小的粒子，使用权值大的粒子代替），这三步构成了粒子滤波的基本算法。 SIRF(Sample Importance Resampling Filter)算法是粒子滤波的一种基本算法。(Particle filter matlab simulation program)
