说明：  burg算法对现代谱进行估计伯格算法（burg algorithm)一种直接由已知的时间信号序列计算功率谱估计值的递推算法。由于是J．P·伯格提出的，故得名伯格算法。(Burg algorithm is a recursive algorithm which can calculate the power spectrum estimation directly from the known time signal sequence. Because it is proposed by J.P. Berg, it is named Berger algorithm.)

matlab中LMI工具箱gevp的详细用法(matlab LMI toolbox gevp detailed usage)

说明：  基于倒谱法的基音周期检测，有着不错的参考意义。(The pitch period detection based on cepstrum method has a good reference value.)

ook调制，用matlab实现OOK调制(ook modulation, with the realization of OOK modulation matlab)

说明：  基于matlab的编程，信道仿真的，很好很强大(Matlab-based programming, channel simulation, very good very strong)

用G_P方法计算关联维数，设置步长为100，可以自行设定。(Correlation dimension calculation method used G_P set in steps of 100, you can set their own.)

设计一个采用 2ASK（OOK）调制的数字通信系统，给定载波频率为码元速率的2倍，产生二进制随机数据，并仿真其对应的 2ASK 调制波形，分析其频谱。所产生的调制波形加入不同信噪比的白噪声，再观察其波形和频谱变化。(Design of a use 2ASK (OOK) modulated digital communication system, a given carrier frequency is twice the symbol rate, to generate a random binary data, and simulate its corresponding 2ASK modulation waveform, the spectrum analysis. Modulated waveform generated by white noise with different noise ratio, and then observe its waveform and spectrum changes.)

After we calculate the R peaks of the ecg signal, we identify different criteria : a) Heart rate. b) Regularity of the R-R peaks (Look at the R-R distances). 1. Regular (are they equidistant apart). 2. Irregular. c) Rhythm 1. Tachycardia ==> Fast. 2. Bradychardia ==> Slow. 3. Normal.
