说明：  Fast_Infogram MATLAMB程序，包含时域谱负熵、频域谱负熵和平均谱负熵(Fast_Infogram MATLAMB program, including time-domain spectral negativity, frequency-domain spectral negativity and average spectral negativity)

Speech Recognition Using DTW This is a English/Persian 0~9 digit and some primary English/Persian command recognition system which use Dynamic Time Warping (DTW). Code is developed in MATLAB 6.5 and can used in Windows platform. Program has two versions, a command line one and a GUI version. The GUI one is compatible with version 6.5 of MATLAB. It can record sound stream online or can recognize recorded file. A simple an necessary help also integrated in the GUI. To start using this program run Start.m script.

说明：  话到变送器和其计算复杂度 类似于MRRC。比起MRRC,如果总数 辐射功率是保持不变的,发送的多样性 方案具有3-dB不利(less system, using two transmit antennas at the base stations instead of two receive antennas at all the remote terminals. The scheme does not require any feedback from the receiver to the transmitter and its computation complexity is similar to MRR)

对于周期图的功率谱估计,当数据长度N太大时,谱曲线起伏加剧, 若N太小,谱的分辨率又不好,因此需要改进。两种改进的估计法是 平均周期图法和平滑平均周期图法。Bartlett法:Bartlett平均周期图 的方法是将N点的有限长序列x(n)分段求周期图再平均。(For the power spectrum estimation of the periodogram, when the data length N is too large, the spectral curve fluctuation intensifies,   If N is too small, the spectral resolution is not good, so need to be improved. The two improved estimates are   Average Period Graph and Smooth Mean Period Graph. Bartlett method: Bartlett average cycle chart   Is to re-average the finite-length sequence x (n) of N points by periodogram.)
