一个好使的采用特征点匹配的指纹识别

power spectrum analysis of the audio fingerprint system(power spectrum analysis of the audio finger rprint system)

说明：  非性多变量系统递归辨识算法，同时, 也对这些算法的估计一致性问题进行了讨论，具有效果还可以(Recurrent identification algorithms for non-linear multivariable systems are discussed. The estimation consistency of these algorithms is also discussed. The results show that the algorithm is effective and can be used to identify non-linear multivariable systems.)

指纹识别是一种生物特征识别方法

卡尔曼滤波器，用simulink建立滤波器模型，并带有.m文件(Kalman filter, filter model with simulink established, and with. M file)

A multiplexing system with NT transmit and NR equals NT receive antennas is designed. The main challenge fo systems lies in the non-orthogonality of the transmission channel. This can be solved by turbo processing. Turbo channel encoder is used for converting the bits in its suitable form. Then different M-ary QAM is compared.

kanon歌曲matlab实现，运行可以听到kanon歌曲的旋律(The kanon Song matlab realize, running can hear the the kanon song' s melody)

cpsd 单独子函数，可编译后直接应用于自己的程序，方便快捷，使用fftw库(cpsd separate sub-functions can be applied directly after compiling its own procedures, convenient use fftw library)

基于最小二乘法的系统辨识方法，包括了一次算法和循环迭代算法，含噪声辨识(Based on least squares system identification methods, including an algorithm and iteration algorithm with noise identification)

常规波束形成，均匀加权，给个权重因子，线列阵常规波束形成。(Conventional beamforming, uniform weighting, to a weight factor, the conventional line array beamforming.)
