In Analog systems, the chief objective is the fidelity of reproduction of waveforms, hence, the suitable performance criterion is the output signal to noise ratio. The choice of this criterion stems from the fact that the signal to noise is related

Outage probability is a crude measure of performance. It is defined as the probability when mutual information is less than the given threshold.
The importance of outage probability is that when outage occurs, there is more likely to have decod

在信道错误概率都为 =0.5的BEC中:当码长N=28逐渐增加到码长N=211时，信道容量I（WN(i)）趋向于0和信道容量I（WN(i)）趋向于1的点数越来越多,也越来越明显了。这说明了，当码长N不断增大时，这种往两边信道聚集的现象越来越突出,到了最后对于信道中的容量,将会有一部分信道的容量向值为“1”的信道中逐渐聚集，概率约为 ；而另外的一部分信道容量向值为“0”的信道中逐渐聚集，概率约则为 ，这就是我们所说的信道极化现象(In the BEC of the channel error pr
