a simple implementation for 4 16 64 QAM plots to obtain simulated and theoretical results for OFDM system

一段关于esprit算法的仿真程序，对结果进行绘图(esprit algorithm simulation program)

mat lab code for elim elim E*A = R factorization. E = elim(A) returns the elimination matrix E that gives the reduced row echelon form E*A = R. If A is square and invertible, then E = inv(A). [E, R] = elim(A) returns the elimination matrix E and the reduced row echelon form R.

matlab与excel间的数据交换,主要是关于两者之间数据相互交换的(data exchange between matlab and excel)

计算wigner-randon变换的频域解线调代码(Transform the calculation of Wigner-Randon the frequency domain dechirp code)

传输矩阵法计算啁啾光栅反射谱 本节中给出传输矩阵法计算啁啾光栅反射谱和 时延的完整M at lab 程序实例, 本段代码在 M at lab513 和W indow s2000 环境中运行通过。运行结果如图8 所示。可以改变光栅长度、有效折射率、折射率调制深度、啁啾系数等参数来获得不同参数下光栅反射谱和时延曲线。如果打开“％ 切趾”行的屏蔽符“％ ”则可得到切趾后光栅反射谱和时延特性曲线, 此时计算所得的曲线将比图8 中所示的曲线平滑很多。(Transfer matrix method to calculate reflection spectrum of chirped grating is given in this section transfer matrix method to calculate chirped grating reflection spectrum and the delay of a complete example of M at lab procedures, the above code in M at lab513 and W indow s2000 environment to run through. The results shown in Figure 8. Can change the grating length, the effective refractive index, refractive index modulation depth and chirp coefficient parameters to obtain different parameters of grating reflection spectrum and the time delay curve. If you open Apodization line shielding Fu can be grating after apodization reflection spectrum and the delay characteristic curve, the curve at this time will be calculated as shown in Figure 8 a lot of curve smoothing.)

Many algorithms for PQRST feature extraction have been reported in the literature, especially algorithms for finding the QRS complex [Pahlm and Sornmo, 1984] [Hamilton and Tompkins, 1986]. In this section, only the feature extraction algorithm used in this work is described.
