极化码是编码领域的一个新的研究方向。设基本信道的参数发生变化,一定会对极化码的性能造成影响,研究发现极化码在二进制删除信道(BEC)下巴氏参数(Z参数)具有单调性,且假设给定一个Z参数的门限γ,那么Z≤γ的信道定义为可用信道,发现若基本信道的擦除符号ε变为ε-▽ε时,经证明发现原来可用的信道仍然全部是可用信道。另外经过研究发现极化码在BEC信道下虽然不具备针对不同的ε参数有全排序的能力,但是具有部分可排序的性质。
Polarization coding is a new research field in the field of coding. If the parameters of the basic channel are changed, the performance of the polarization code will certainly be affected. It is found that the P parameter (Z parameter) of the polarization code is monotonic in the BEC, and that given a Z parameter Threshold γ, then a channel of Z ≤ γ is defined as a usable channel and it is found that if the erasure symbol ε of the basic channel becomes ε - ▽ ε, it turns out that all the available channels are still found to be available channels. In addition, it has been found through research that although the polarization codes do not have the ability of full ordering for different ε parameters under the BEC channel, they have partial sorting properties.
