正交频分复用是一种多载波宽带数字调制技术。相比一般的数字通信系统， 它具有频带利用率高和抗多径干扰能力强等优点，因而适合于高速率的无线通信系统。( OFDM Simulator -------------------------------------------------------------------------------- MIMO OFDM Simulator: OFDM.m: OFDM Simulator (outer function) create_channel.m: Generates a Rayleigh fading frequency-selective channel, parametrized by the antenna configuration, the OFDM configuration, and the power-delay profile. svd_decompose_channel.m: Since full channel knowledge is assumed, transmission is across parallel singular value modes. This function decomposes the channel into these modes. BitLoad.m: Apply the bit-loading algorithm to achieve the desired bit and energy allocation for the current channel instance. ComputeSNR.m: Given the subcarrier gains, this simple function generates the SNR values of each channel (each singular value on each tone is a separate channel). chow_algo.m: Apply Chow s algorithm to generate a particular bit and energy allocation. EnergyTableInit.m: Given the SNR values, form a table of energy increments for )

统计瑞利衰落特性,得到其幅度密度函数图。更进一步了解瑞利衰落特性。(Analyse the character of rayli fading,getting the CDF of teh rayli fadign.)

matlab 从脉搏信号中计算心率的小程序，很好用！！(matlab calculate the heart rate signal from the pulse of the small program, easy to use! ! )

计算多重分形非趋势波动分析matlab程序,能量谱分析计算,GSM中GMSK调制信号的产生。( Calculation multifractal detrended fluctuation analysis matlab program, Energy spectrum analysis and calculation, GSM is GMSK modulation signal generation.)

说明：  matlab下的有用的时频分析工具箱，包括各类调频信号的生成，频率相位提取(matlab useful under the time-frequency analysis toolbox, including the generation of various types of FM signals, frequency-phase extraction)

设有连续时间周期信号，它的周期为T，角频率，且满足狄里赫利条件，则该周期信号可以展开成傅里叶级数，即可表示为一系列不同频率的正弦或复指数信号之和。(With continuous time periodic signal, its period is T, the angular frequency, and to meet the Diliheli conditions, the periodic signal can be expanded into a Fourier series, can be expressed as a range of different frequencies of sinusoidal or complex exponential signal and.)

这个matlab程序实现了目标对象的图像分割与提取技术，附件里的程序以车牌的检测与识别为例，效果非常好。(Matlab program achieved the target of image segmentation and extraction technology, the annex of the procedures to license plate detection and recognition as an example, has very good results.)

这个是关于TDOA的源程序，里面的文件，时间长了，也忘记都是干啥的，自己研究下借鉴(This is about the source of TDOA, inside the file, long time, and also forget are doing, their own research under the draw)
