Rayleigh-channel

The method mainly consists in considering a reference normal ECG segment and input ECG (unknown behavior) segment. Each segment of the input ECG T is compared to the reference segment using SEA. The SEA method outputs a measure in the range [0..1] in terms of the correlation factor that reflects the degree of similarity between the reference and the segment under analysis. Based on this measure, the whole segment is classified as normal or abnormal. A user specified threshold value on the correlation factor c is used for decision

其基本思想是：采用信号与噪声的状态空间模型，利用前一时刻地估计值和现时刻的观测值来更新对状态变量的估计，求出现时刻的估计值。它适合于实时处理和计算机运算。 (The basic idea is: use of signal and noise state-space model, the estimated value of the previous time and are always observations to update the estimated state variables, find an estimate of time there. It is suitable for real-time processing and computing.)

2FSK是利用数字基带信号控制在波的频率来传送信息。经过调制后的2FSK数字信号通过两个频率不同的带通滤波器f1、f2滤出不需要的信号，然后再将这两种经过滤波的信号分别通过包络检波器检波，最后将两种信号同时输入到抽样判决器同时外加抽样脉冲，最后解调出来的信号就是调制前的输入信号。(gudi hduidf hdag sdd w)
