在本文中，我们应用极化码的高斯退化中继信道。我们研究的条件所需满足的代码，并提供了一个有效的方法来构造它们。中继-目的地链路是特殊的，因为噪声是两个分量之和：高斯噪声和来自源的信号。我们研究这个链接，并提供对数似然表达式使用的极化码检测器。仿真结果表明，高码率、大码字长度的极化码比其他性能较好的极化码更接近理论极限。
In this paper we apply polar codes for the Gaussian degraded relay channel. We study the conditions to be satisfied by the codes and provide an efficient method for constructing them. The relay-destination link is special because the noise is the sum of two components: the Gaussian noise and the signals from the source. We study this link and provide the log-likelihood expression to be used by the polar code detector. We perform simulations of the channel and the results show that polar codes of high rate and large codeword length are closer to the theoretical limit than other good codes.
