关于FFT的一个例子，Short time FFT with octave smooth by Matthes(An example of FFT on, Short time FFT with octave smoothby Matthes)

totally fuzzy for using at matlab, you can make it better with this function

说明：  GMM的优化，用EM算法实现高斯混合模型(GMM optimization algorithm EM)

说明：  calculates Fourrier transform.

基于滑模观测器的无位置永磁同步矢量控制，simulink仿真模型！(sensorless pmsm SVPWM Sliding mode observer)

主要内容包括波束形成、DOA估计、相干信号的DOA估计、二维DOA估计、宽带阵列信号处理、阵列多参数估计等(The main contents include beamforming, DOA estimation, coherent signal DOA estimation, two-dimensional DOA estimation, wideband array signal processing, array multi parameter estimation, etc.)

music算法在谱估计中（即经典算法）在高信噪比和多阵元情况下有较高的估计性能和精度。本程序主要是实现此算法。(music spectrum estimation algorithm (ie the classical algorithm) in the high SNR and multi-array cases have a higher estimation performance and accuracy. This procedure is mainly to achieve the algorithm.)

The paper concludes with an implementation of linear prediction using two different types of signal. It is hoped that the balance between theory and practical will allow the reader for easy assimilation of this technique

语音增强，倒谱，端点检测，共振峰检测，去噪(Speech enhancement, cepstrum, endpoint detection, formant detection, denoising)

说明：  k-g算法，NCPCG算法，KG-CP算法的信干比对比分析(kg algorithm, NCPCG algorithm, KG-CP algorithm SIR comparative analysis)
