Abstract:

As the first type of channel codes which has achieved the channel capacity, polar codes are an important candidate for the 6G data transmission. A polar coded framework of the non-orthogonal multiple access (NOMA) to the 6G system is proposed. In this framework, the scheme for the polar coded coordinated NOMA is investigated to fulfill the requirement of high-capacity transmission of 6G systems. Furthermore, the scheme for the polar coded non-coordinated NOMA can achieve the ultra-high reliable access to the 6G internet scenario. All these schemes indicate that polar coded NOMA techniques can dramatically boost the performance of 6G wireless transmission and has a broad application prospect.

Key words: polar codes, channel polarization, coordinated NOMA, non-coordinated NOMA, polar coded NOMA
