LDPC码的matlab仿真程序，希望对大家有用，不客气，(LDPC codes matlab simulation program, in the hope that useful, at worst,)

mimo-ofdm系统中MMSE信道估计算法(mimo-ofdm system MMSE channel estimation algorithm)

控制系统仿真分析软件。请从mainControl.m文件开始。(Autocontrol system simulation software with GUI interface.)

在程序中用一般的MUSIC方法估计了信号的频谱，从两图中可看出在信号各频率处，频谱的峰值较大，故能明显的与噪声相区别，可在一定程度上避免在信号幅度较小时信号被噪声淹没的情况。(MUSIC method general procedures used to estimate the spectrum of the signal, it can be seen from the two graphs in the signal at each frequency of the spectrum peak larger, and it could be significantly distinguished from noise in the signal can be avoided to some extent a lesser extent, the signal is noise submerged.)

先建立lorenz吸引子，在分别做出X,Y,Z的时序图，最后用X重构向空间，在TAU取不同值时，图的效果也不一样(Lorenz X phase three-dimensional reconstruction of attractor figure)

C4.5算法 matlab实现的，感觉还可以，大家可以看看！(the implementation of C4.5 using matlab)

不同条件下DOA与波束角度的关系，适合初学自适应信号处理的朋友(for beginners about array signal processing)

用费涅尔波带片模拟透镜成像，光波衍射模拟(toll Nieerbei zone plate imaging lens simulation, simulation wave diffraction)
