Algorithm for Generating Random Number with Multi-dimensional Discrete Distribution

该文档给出了通信原理中的数字调制和解调的matlab程序代码，如BPSK,QPSK,QAM等等调制方式。(the document is a communication principle of digital modulation and demodulation of the Matlab code. such as BPSK, QPSK, QAM modulation mode, and so on.)

时频分析中的cohen类中最基本的双线性时频分布式wigner-ville分布，由于在该分布中不含窗函数，因此避免了短时窗傅里叶变换时间分辨率、频率分辨率相互牵制的矛盾(Time-frequency analysis of the Cohen class of bilinear time-frequency distribution is the most basic Wigner-Ville distribution, because the function in the distribution is not included in the window, so as to avoid the contradiction of short-time window Fourier transform time resolution, frequency resolution of each other)

自己用的时域特征提取方式，包含均值，均方根值，歪度，峭度，峰值指标，阈值裕值指标，峭度指标等，然后用RBF做聚类(The method of feature extraction in time domain includes mean value, root mean square value, skewness, kurtosis, peak value index, threshold margin index, kurtosis index, etc. Then RBF is used for clustering.)

PSO源代码，求解单目标优化问题，本代码用于求解非线性方程组问题(PSO source code)

一种超声波发射系统，包括探测信号、同步信号BPSK信号的发射过程，用C代码编写，在CCS软件上实现。(An ultrasonic transmitter system, including firing process detection signal, synchronizing signal BPSK signal, written in C code that implements the CCS software.)

用于模拟相移光纤光栅(FBG)的传输特性,包括多相移光栅(Used to simulate the phase-shift fiber Bragg grating (FBG) of the transmission characteristics, including multi-phase-shift grating)

简单介绍了RLS算法(递推最小二乘算法)，附带程序能够实现RLS的仿真，并且仿真效果较好。(A brief introduction of the RLS algorithm (recursive least squares algorithm), RLS can be achieved with the simulation program and simulation is better.)
