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碼逼近香農限的性能具有強有力的理論支撐。

2、polar極化碼具有明確的構碼方法。

3、polar極化碼它的編譯碼復雜度相對較低。

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(guò)程高并行度不容易實(shí)現，導致其時(shí)延相對較大。原因是SC譯碼算法的機制為逐比特譯碼。

polar極化碼的理論基礎是：

并且Polar 碼的理論基礎就是信道極化。信道極化包括信道組合和信道分解部分。當組合信道的數目趨于無(wú)窮大時(shí)，則會(huì )出現極化現象：一部分信道將趨于無(wú)噪信道，另外一部分則趨于全噪信道。

這種現象就是信道極化現象。無(wú)噪信道的傳輸速率將會(huì )達到信道容量 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用了這種現象的特性，利用無(wú)噪信道傳輸用戶(hù)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
