A Novel Downlink IM-NOMA Scheme
IEEE Open Journal of the Communications Society, 2021 In the next generations of communication systems, resources' scarcity devolves to a more critical point as a consequence of the expected massive number of users to be served. Furthermore, the users' contradicting requirements on quality of service forces

Spatially Modulated Code-Division Multiple-Access for High-Connectivity Multiple Access [PDF]
IEEE Transactions on Wireless Communications, 2019 In order to take the advantages of spatial modulation (SM) and support the multiple-access (MA) communications requiring high connectivity, we integrate the SM with DS-CDMA to propose a SM/DS-CDMA scheme, which is in favor of attaining both antenna diversity and frequency diversity. Associated with the SM/DS-CDMA scheme, a range of linear and nonlinear

Outage Performance Analysis of RSMA-Aided Semi-Grant-Free Transmission Systems
IEEE Open Journal of the Communications Society, 2023 In this paper, we analyze the outage performance of a rate-splitting multiple access (RSMA)-aided semi-grant-free (SGF) transmission system, in which a grant-based user (GBU) and multiple grant-free users (GFUs) access the base station by sharing the ...
