Performance Analysis of a Spatial Modulation Aided Cooperative NOMA System
In this letter, a novel communication scheme termed spatial modulation aided cooperative non-orthogonal multiple access (SM-CNOMA) is proposed for multiple-input and multiple-output (MIMO) downlink scenarios. In the SM-CNOMA system, the base station (BS) transmits information to three users across two time-slots, encompassing two near users (NUs) and a single far user (FU). Notably, NUs operate in a half-duplex mode and employ joint signal detection during the cooperative phase for decoding, and forward FU information through index modulation (IM). Bit error rate (BER) and ergodic sum-rate metrics are derived, by considering inter-user interference (IUI), of the proposed SM-CNOMA system. The impact of various system parameters, such as the number of transmit and receive antennas, is thoroughly analyzed within the SM-CNOMA framework. The presented results demonstrate that SM-CNOMA outperforms conventional CNOMA with three users and the precoded CNOMA (PCNOMA) systems. This letter contributes valuable insights into the potential benefits of SM-CNOMA in MIMO downlink communications, establishing its efficiency in mitigating interference and enhancing the overall system performance.
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.
