Abstract—The purpose of this article is to analyze the capacity of a discrete-continuous communication channel (DC-channel) as applied to nonorthogonal multiple access (NOMA) systems. In this work, an expression is obtained for the individual mutual information of a DC-channel in communication systems with nonorthogonal access, which makes it possible to analyze the capacity of the DC-channel individually for subscribers of NOMA systems. Its effectiveness for analyzing group signals of NOMA systems is shown, examples of its use are given, and capacity characteristics for NOMA subscribers are obtained as well.

非正交多址通信系统中的单个信道容量

摘要--本文旨在分析应用于非正交多址接入（NOMA）系统的离散-连续通信信道（DC-channel）的容量。在这项工作中，我们得到了非正交接入通信系统中直流信道的单个互信息的表达式，从而有可能对 NOMA 系统用户的直流信道容量进行单个分析。本文展示了该方法在分析 NOMA 系统分组信号时的有效性，并给出了使用该方法的示例，同时还获得了 NOMA 用户的容量特征。
