梳状导频方式下OFDM系统的LS、LMMSE算法比较(Comb Pilot OFDM system under LS, LMMSE algorithm)

Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.

随机子空间的matlab主程序代码，可以实现高精度的信号辨识。按照《基于随机子空间和最小二乘法的介质损耗角测量方法》、常军博士论文《随机子空间方法在桥梁模态参数辨识中的应用研究》编写。(Stochastic subspace matlab main code, you can achieve high-precision recognition. Accordance with the " stochastic subspace-based least-squares method and dielectric loss angle measurement methods" , regular army doctoral thesis " stochastic subspace identification of modal parameters of the bridge in the applied research" to write.)

经验模式分解改进代码，基于经验模式分解的一种改进 经验模式分解 matlab(Empirical Mode Decomposition improve code)

按照给定指标采用模拟低通滤波器（巴特沃思低通或者切比雪夫低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(According to a given target analog low-pass filter (Butterworth or Chebyshev low-pass low-pass) to approximate the ideal analog low-pass filter, then through the bilinear transformation method to digitize the analog filters, digital filters has been .)

本代码实现动态物体的识别与跟踪，但注意本代码只能检测单物体且背景是静止不动的。(The code identification and tracking moving objects, but note that this code can only detect a single object and the background is stationary.)

说明：  计算不同采样率的两个地震道的互相关函数，两个地震道的采样是不一样的。(Different sampling rates of the two seismic cross-correlation function)
