基于s函数的无刷直流电机双闭环仿真 希望对大家有用 参数没有调整(S function based on double closed-loop simulation of brushless DC motor)

说明：  包括直接序列扩频CDMA的调制和解调函数(Including direct sequence spread spectrum CDMA modulation and demodulation function)

一种分析混沌信号的多重分形谱的简单程序，尤其分析网络流量中尤为有效

本人用MATLAB 来运算小世界的复杂网络。大家请参阅及分享意见。(use matlab to simulate the small-world network.)

说明：  读取图像lena.tif，进行DCT变换，每个图像块保留10个DCT系数进行重构图像，比较重建图像与原始图像的差异。(Read the image lena.tif, the DCT transform, each image block of 10 DCT coefficients to retain the reconstructed image, reconstructed image compared with the original image differences.)

自己写的关于matlab的规则LDPC编码以及重复码码率与SNR的关系图，希望对大家有用，谢谢(Write their own rules on Matlab LDPC codes, the hope that useful, thank you)

设计一个四用户的扩频通信系统，扩频增益为N=16，采用Walsh码进行直接序列扩频，BPSK调制，无线信道为AWGN信道。在接收端进行解扩，解调，判决，通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(Designed a four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)

这个程序是一种简单的协作通信的，基于ofdm传输的Alamouti空间的空时码设计(This program is a simple collaborative communications, based on ofdm transmission of the Alamouti space time code design)

PID控制的仿真,<<PID控制与应用>>课程的作业.SIMULINK格式(PID control of the simulation,)

说明：  对于一个存储了五门课成绩的txt文本，进行数据读取、数据分离、画出变化曲线。(For a TXT text that stores the scores of five courses, data reading, data separation and drawing change curve are carried out)
