极大似法编的系统辨识malab源码，这是基于概率的方法，可以直接拿来作为极大四然的程序短，应用于各种极大四然的实例(Maximum method of system identification malab source)

说明：  数字信号处理 典型序列的Matlab实现和序列的卷积运算(Digital signal processing to achieve a typical sequence of Matlab Convolution and serial computing)

this code is a matrix with 4 operation

本次实验是无线楼宇数据传输仿真，即在楼内实现点对点的无线数据通信，需要获得的关键是两点之间的距离和楼层衰减。通过了解914M的楼宇通信特性，建立楼宇数据通信系统的仿真模型，采用无线收发芯片NRF905,实现楼宇内的数据通信仿真分析。 (this experiment is building wireless data transmission simulation, in the building of peer-to-peer wireless data communications, need, the key is the distance between two points and the floor attenuation. 914 M by understanding the communication characteristics of the buildings, the establishment of building data communications system simulation models, adoption of wireless transceiver chip NRF905 achieve buildings on the simulation analysis of data communications.)

谱减法是利用噪声的统计平稳性以及加性噪声与语音不相关的特点而提出来的。即让有语音期间噪声幅度谱的期望值与无语音间隙噪声的幅度谱的期望值相等。(Spectral subtraction method is the use of stationary noise statistics and the additive noise and speech characteristics not related to the initiative. During that speech so that the expected value of noise amplitude spectrum and noise-free audio gap equal to the expected amplitude spectrum.)

《MATLAB神经网络30个案例分析》中的第一个例子，案例1 BP神经网络的数据分类-语音特征信号分类。希望对大家有用！ (" MATLAB neural network 30 case studies" in the first example, case 1 BP neural network data classification- speech feature signal classification. I hope useful!)

说明：  遗传算法的一个matlab实例，运行测试通过(A genetic algorithm matlab example, run the test)

自己编程产生一种二进制频率调制信号，为数字调制信号的识别做准备。( programming to produce a binary frequency modulation signal, the recognition of digital modulation signals in preparation.)
