short program that computes a rect

采用matlab实现的wsn节点算法，对于研究wsn非常有好处。虽然有很多人有类似的代码，但是这个代码比较相信。(Using matlab to achieve wsn node algorithm for the study of wsn very good. Although many people have similar code, but this code is to believe.)

该计算代码主要对msk,fsk,ask等常规调制信号的循环谱进行了仿真，可以进一步补充，谢谢大家分享。(This calculation code mainly cyclic spectrum msk, fsk, ask other conventional modulation signal simulation, can be further supplemented, thank you share.)

自适应均衡器的仿真程序：基于抽头系数，遗忘因子，噪声方差，初始化的延迟信号设计输入信号，利用LMS 算法建立自适应均衡器滤波信号。(Adaptive equalizer simulation program: based tap coefficients, forgetting factor, noise variance, the initialization of the input signal delayed signal design, the use of the LMS algorithm to establish adaptive equalizer filter signal.)

very useful book about MIMO-OFDM wireless communications with matlab

BPSK 与QPSK 调制解调系统的Matlab 仿真程序,发送滤波器与接收滤波器均为根升余弦滚降滤波器；信道噪声为加性高斯白噪声 绘制BPSK 与QPSK 调制下的误码率与信噪比曲线图，并与理论曲线进行对比(BPSK and QPSK modulation and demodulation system Matlab simulation program, send and receive filters are root raised cosine filter roll-off filter channel noise, BER and SNR draw BPSK and QPSK modulation under additive white Gaussian noise than the graph and compare with the theoretical curve)

调制识别是非协作通信中的关键技术之一，在电子对抗、软件无线电等领域 应用十分广泛。该过程介于信号检测与解调之间，由于对传输信号没有过多的先 验信息以及在接收端有很多未知的参数，例如：信号功率，载波频率和相位偏移， 时间信息等，导致对调制方式的盲识别是一项很困难的任务。此外，实际中存在 多径衰落、频率选择性和时变信道等问题，使得这项任务变得更具有挑战性。 (The modulation recognition is one of the key technologies of the non-cooperative communication, such as electronic countermeasures and software defination radio, therefore it is such a significant discipline and orientation in the research of communication field. Obviously, without enough knowledge in transmitter and verified parameters about receivers, for example signal power, carrier frequency and phase offsets and so force, it is hard to get the modulation of blind identification. What is more, for the sake of the multipath fading, frequency-selective and time-varying channels in the real scenarios the task is even harder. )

本代码为多智能体系统的一段MATLAB仿真源文件，希望大家学习。(This code for agent system of a MATLAB simulation source file, hope everybody to learn.)

说明：  matlab写的运动检测 自动实现 十分有用的代码 值得学习！(Motion detection matlab automatically write the code should be very useful to learn!)
