OFDM系统各个信道估计算法仿真，包括：基于QAM16块状导频的LS、LMMSE、LSMMSE(SVD)；基于QAM16梳状导频的LS等。(Respective channel estimation for OFDM systems simulation algorithm, comprising: a block-based pilot QAM16 LS, LMMSE, LSMMSE (SVD) QAM16 based comb-like pilot LS.)

我的智囊团项目完整的源代码,可以作为HSS学习的例子,但是注意要导入相应的包! (I think-tank project the complete source code can be used as HSS learning example, but note that you want to import the appropriate package!)

利用谱减算法实现对航空录音的处理。主要思想是相对语音进行加噪声，然后再利用算法去噪声，比较前后信噪比的变化。根据实验结构，去噪效果明显。(The use of spectral subtraction algorithm for handling aviation record. The main idea is to increase the relative voice to the noise, and then use the algorithm to noise, signal to noise ratio before and after the change. According to the experimental structure, de-noising effect is obvious.)

一些数学模型中的算法程序，附带编码，matlab(Some mathematical model algorithm program with code, matlab)

该函数实现了cantor三分集的生成，例如输入cantor(0,0,1,0)即可产生[0,1]区间的三分集(The function implements the generation of the cantor ternary set, for example, enter the cantor (0,0,1,0) to generate the third set of the interval [0,1] )

心电信号R波检测的函数，包括降采样，滤波，希尔伯特包络提取三个预处理步骤。其中R波根据阈值检测，相对不应期要根据具体信号适当调整.(ECG R-wave detection functions, including down-sampling , filtering, Hilbert envelope extracted three pretreatment steps. Wherein R wave detection based on a threshold , the relative refractory period should be adjusted according to the specific signal . )
