摘要

本文提出了一种新的阻抗域非正交多址（ID-NOMA），以克服传统功率域非正交多址（PD-NOMA）的问题。提出的ID-NOMA集成了阻抗匹配电路（IMCs）和基于阻抗的功率衰减增强（I-PAR）。IMC值来自源和负载IMC，而I-PAR通过使用I-PAR系数衰减用户信号。数值结果表明，由于I-PAR的有效性，所提出的ID-NOMA在遍历容量（EC）和中断概率（OP）方面优于PD-NOMA。

A Novel Impedance Domain Non-Orthogonal Multiple Access

This letter proposes a novel impedance domain non-orthogonal multiple access (ID-NOMA) to overcome problems on conventional power domain NOMA (PD-NOMA). The proposed ID-NOMA integrates impedance-matching circuits (IMCs) with impedance based power attenuation reinforcement (I-PAR). The IMC values are derived from source and load IMCs while I-PAR attenuates user’ signals by using I-PAR coefficients. The numerical results show that the proposed ID-NOMA outperforms PD-NOMA in terms of ergodic capacity (EC) and outage probability (OP) owing to the effectiveness of I-PAR.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
