In the BEC of the channel error probability is =0.5: when the code length N=28 is gradually increased to the code length N=211, the channel capacity I (WN (I)) tends to 0 and the channel capacity I (WN (I)) more and more points to 1, and more and more obvious. This shows that, when the code length N is increasing, the phenomenon of gathering on both sides of the channel becomes more and more prominent. At the end of the capacity of the channel, some channel capacity will gradually gather in the channel with the value of "1", the probability is about, and the other part of the channel capacity is gradually gathered in the channel with the value of "0". The probability is about that, which is what we call channel polarization.
