polar極化碼優(yōu)缺點(diǎn)

polar極化碼優(yōu)缺點(diǎn)分別是：

polar極化碼優(yōu)點(diǎn)是：

1、 Polar碼逼近香農(nóng)限的性能具有強(qiáng)有力的理論支撐。

2、polar極化碼具有明確的構(gòu)碼方法。

3、polar極化碼它的編譯碼復(fù)雜度相對(duì)較低。

4、polar極化碼采用合適的譯碼方法如（CA-SCL算法），其性能可超越最好的LDPC碼與Turbo碼。

polar極化碼缺點(diǎn)是：polar極化碼譯碼過程高并行度不容易實(shí)現(xiàn)，導(dǎo)致其時(shí)延相對(duì)較大。原因是SC譯碼算法的機(jī)制為逐比特譯碼。

polar極化碼的理論基礎(chǔ)是：

并且Polar 碼的理論基礎(chǔ)就是信道極化。信道極化包括信道組合和信道分解部分。當(dāng)組合信道的數(shù)目趨于無窮大時(shí)，則會(huì)出現(xiàn)極化現(xiàn)象：一部分信道將趨于無噪信道，另外一部分則趨于全噪信道。

這種現(xiàn)象就是信道極化現(xiàn)象。無噪信道的傳輸速率將會(huì)達(dá)到信道容量 I (W )，而全噪信道的傳輸速率趨于零。Polar 碼的編碼策略正是應(yīng)用了這種現(xiàn)象的特性，利用無噪信道傳輸用戶有用的信息，全噪信道傳輸約定的信息或者不傳信息。

pole和polar有什么關(guān)系

兩個(gè)都有極的意思，pole一般用作名詞“極地，桿”，而polar一般用作形容詞“極地的”比如Polar bear
