OFDM系统中的载波频偏估计算法及其性能分析(ofdm algorithm)

利用9元平面线阵对空间4个声源进行定位，信噪比为10db，music 算法，谱峰较尖锐(9 elements planar array to localize 4 signal DOAs, MUSIC method ,snr is 10db, well spectral peak )

写的MATLAB程序实现傅里叶变换大家可与参考一下(MATLAB program written by Fourier transform we can refer to)

Matlab产生ECG波形的程序，值得一看。(Use Matlab to generate ECG wave )

说明：  循环谱估计算法，有FAM和SSCA，利用谱自相关函数或者互谱相关函数，可以对循环谱循环进行学习或者分析。(Cyclic spectrum estimation algorithms, including FAM and SCA, can learn or analyze the cyclic spectrum cycle by using spectral autocorrelation function or cross-spectral correlation function.)

performs edge detection well

说明：  基于双耦合Duffing振子的随机相位正弦信号检测 采用双耦合混沌振子阵列实现了随机相位微弱正弦信号的检测，在此基础上，提出了新的检测方法，即利用单个耦合混沌振子，通过临界及周期状态 的变化检测随机相位微弱正弦信号并大致估计信号相位范围，该方法比双耦合混沌振子阵列法简单，更易于实现。(Based on double coupled Duffing oscillators random phase sine signals detected by two coupled chaotic oscillator arrays to achieve a random phase weak sinusoidal signal detection, in this basis, the proposed new detection methods, namely the use of a single coupled chaotic oscillators, through the critical and the cycle random phase state change detection and generally weak sinusoid signal phase estimated the scope of the method than the two-coupled chaotic oscillators array method is simple and more easy to implement.)

4次牛顿差值多项式的matlab实现 数值分析实习作业(4 Newton polynomial difference)

将txt中的数据导入matlab中并形成x1,y1,x2,y2...，的变量名，方便管理和调用(Read data in txt file into matlab and generate variables like x1,y1,x2,y2 and so on. Manage the variables for convenience)

说明：  数字预失真的程序，很不错的，运用直接训练法，效果不错(Digital pre-distortion process, very good, the use of direct training method, good results)
