这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。希望对大家有帮助！ (This is based on the space-time block codes of MIMO_OFDM communication system simulation design. This system includes QPSK demodulation, IFFT modulation, space-time decoding, based on the training symbol of channel estimation and other communications module. We want to help!)

用声卡输出的单边带信号源，SSB下边带信号，载波15KHz，输入声音带宽设为300~3.4KHz，SSB调制后输出带宽为11.6K~14.7KHz，可以给SSB解调器实验做信号源了。(Single-sideband signal with the sound output source, SSB below band signal, carrier 15KHz, enter the voice bandwidth set at 300 ~ 3.4KHz, SSB modulated output bandwidth 11.6K ~ 14.7KHz, you can do to the SSB demodulator source experiment the.)

利用MATLAB实现的两个语音的盲信号分离（BSS）~非常有用(MATLAB implementation of the two voice Blind signal separation (BSS) ~ very useful)

改程序的功能：基于IMAGE混响模型编写的混响估计程序，条件实在矩形的房子中进行的(Change program features: based on IMAGE reverberation model reverberation estimation program written, just rectangular house)

说明：  作为初学者的典范,但是程序有很些许错误，还希望高手指点，特别是运行时，每次出的结果不一样，更希望高手指点！(this project is just so so ,it can be used to study by the first learner!certainly ,there are some misstakes, but i can not find it ,because my level is just so so ,i hope you can correcting me !thank you very much !if you correct my project ,pleased send email to hljdx.wuyou@163.com ,thanks! i found my project ,there are so many results when i run ,i do not know why?)

电力系统潮流计算程序(极坐标、带IEEE算例)，内含14，,3,118节点的数据。(Power flow calculation program (polar coordinates with IEEE numerical example), containing 14 data 3,118 nodes.)

该程序仿真了不同的中级转发协议下，系统在不同信道下的中断概率(The program simulation different intermediate forwarding agreement, system in different channel of the interrupt probability)

说明：  基于MATLAB GUI 设计的数字信号处理系统，可以实现基本的信号生成，信号分析和信号滤波以及简单的语音信号处理等功能。其中信号生成模块可实现正弦波、方波、三角波、高斯白噪声、chrip信号的生成和叠加；信号分析模块支持基本的傅氏变换下的频域分析功能；信号滤波模块可以实现数字低通、高通、带通、带阻下的切比雪夫、巴特沃思、椭圆滤波器的设计和滤波处理；语音信号处理模块可以实现音频文件的读取、播放、叠加噪声、滤波等功能。(Based on MATLAB GUI design of digital signal processing system, you can achieve the basic signal generation, signal analysis and signal filtering, and simple voice signal processing and other functions. The signal generating module can realize the sine wave, triangle wave, Fang Bo, Gauss, chrip generation and superposition of white noise signal; signal analysis module supports the analysis function of frequency domain Fourier transform basic conditions; signal filtering module can realize digital low-pass, high pass, band pass, band stop, Butterworth, the Chebyshev elliptic filter design filtering and processing of speech signal processing; module can realize audio files to read, play, adding noise, filtering and other functions.)

给出了用MATLAB语言实现功率谱估计的程序，压缩包内还有原理说明(Given by MATLAB language to achieve power spectrum estimation procedure, there is the principle of compressed packets that)
