Polarization of a Point-to-Point Channel by a Multiple Access Channel: A New Method for Different Channel Polarization

Abstract

The polar coding method which was proposed by Arikan is mentioned. In this article, we will apply this method for the polarization of a general Multiple Access Channel. It will be shown that the polarization of a general Multiple Access Channel with a point-to-point channel can be given a more achievable rate region in the general form. The encoding and decoding complexity for these codes are $$O (N \cdot \log N)$$ and error probability for them is $$O(2^{{ - (N)^{\beta } }} )$$ like the original channel polarization method. Some numerical examples for the proposed method and the competitors are also given.
