simple reduce features used in face recognition using PCA

MIMO-OFDM channel estimation 。是基于mmse准则的，欢迎大家下载使用。(MIMO-OFDM channel estimation. Is based on the MMSE criteria, welcomed everyone download.)

改程序实现了广义旁瓣对消器的仿真，广义旁瓣对消器在阵列信号处理和多用户检测中有重要的应用。(Reform program to achieve a generalized sidelobe canceller in the simulation, generalized sidelobe canceller array signal processing and multi-user detection has important applications.)

非常有用的卫星轨道参数计算模块,很方便进行轨道特性分析。(This is a very useful toolbox for satellite s trajectory parameter computation )

说明：  惯性导航的一些资料，互相学习，互相借鉴一下。(Inertial navigation of some of the material, learn from each other and to be drawn lessons from each other. )

一种基于复合混沌映射的单向Hash函数构造(One-way Hash function construction based on composite chaotic map)

到达时间差（TDOA）源位置估计 -------------------------------------------------- ---------- 使用麦克风信号和自由场模型之间的延迟源位置估计。 TDOA_pairs.m 估计延迟（相对于通道1）通过互相关在时域中。 TDOA_pairs_GCC.m 估计在频域中的延迟（相对于信道1）。采用广义互相关 和SCOT或PHAT（或没有）的均衡。 PHAT的建议，以避免因周期分量的含糊之处。 TDOA_to_sourcepos.m 估计源位置（距离和垂直RESP。水平偏移量）从之间的延迟 阵列麦克风信号。假设一个自由场。(Direction of arrival (DOA) estimation ------------------------------------- Direction-of-arrival estimation with a free field, far field model. Narrowband or broadband (non-coherent) processing. DOA_Bartlett.m Bartlett (delay-and-sum) steered response power. DOA_Bartlett_Octave.m Bartlett (delay-and-sum) steered response power within nth octave frequency bins. DOA_MUSIC.m MUSIC based pseudo beamform power. DOA_MUSIC_Octave MUSIC based pseudo beamform power. nth octave filtering.)

说明：  《MATLAB程序设计教程》，很经典的课件，适合入门(&quot MATLAB Programming Guide&quot , a very classic courseware for entry-)
