可用于matlab的英语语音数据库，用于语音合成与识别(Speech Database)

说明：  随机共振的MATLAB源程序，运用龙哥库塔算法进行的仿真 (sr based on matlab using the longewan function to simulate )

用MATLAB实现电路的运算，可以运用它实现一般的电路基本原理(MATLAB circuit operation, it can be used in general to achieve the basic tenets of the circuit)

OFDM瑞利衰落信道的建模仿真源程序代码，可以仿真单径和多径(OFDM Rayleigh fading channels modeling and simulation source code can be simulated single-track and multi-track)

Costas环是用来解调双边带抑制载波信号的,也是二相或四相移相键控信号解调的专用环路(Costas loop for demodulating the double sideband suppressed carrier signal, two-phase or four-phase shift keying signal demodulation dedicated loop)

Gabor filter has implemented here to find the texture boundary by varying frequency and orientation angle.

这个是在matlab7.6下面运行的一个产生光栅的matlab GUI(simulate the grating using matlab GUI)

着重介绍了OFDM 系统 中的峰值平均功率比（PAR）问题，给出了峰值平均功率比的定义以及高PAR 产 生的原因和它带来的问题，并且分析了OFDM 系统内PAR 的分布，最后对国内 外各种降低PAPR 的方法进行了简单介绍。(Focuses on the OFDM system The peak to average power ratio (PAR), and gives the definition of peak to average power ratio and high PAR production Health reasons and problems it brings, and the analysis of the distribution of the PAR of OFDM system, the last of the domestic A variety of methods to reduce PAPR outside a brief introduction.)

说明：  LLDA，局部线性判别分析，可以降到任意的维度，相比LDA更加优秀(LLDA, Local Linear Discriminant Analysis, can be reduced to any dimension, which is better than LDA.)
