摘要

非正交多址(NOMA)是第五代(5G)蜂窝网络的一种很有前途的方法，它通过在功率域中复用用户来提高频谱效率。在NOMA网络中，接收器面临的一个关键挑战是如何区分同时使用同一频段的单个信号。目前广泛讨论的两种译码方案是连续干扰抵消(SIC)和并行干扰抵消(PIC)。两种方案都是基于不同的算法，即SIC迭代解码和PIC集体解码，从接收信号中减去解码后的信号，从而抑制多用户干扰。本文比较了SIC和PIC方案在基站上的计算时间，并演示了PIC的多线程实现。

Comparison Of Parallel And Successive Interference Cancellation For Non-Orthogonal Multiple Access

Non-orthogonal multiple access (NOMA) is a promising method for the fifth generation (5G) cellular networks as it provides improved spectral efficiency by multiplexing users in power domain. One key challenge for the receivers in NOMA networks is to distinguish the individual signals that use the same band at the same time. Currently, the two widely discussed decoding schemes are successive interference cancellation (SIC) and parallel interference cancellation (PIC). Both schemes suppress the multi-user interference by subtracting the decoded signals from the received signal based on different algorithms, i.e., SIC decodes iteratively and PIC decodes collectively. This paper compares the computation time of SIC and PIC schemes at the base station and demonstrates multi-thread implementation of PIC.
