Outage Probabilities of Orthogonal Multiple-Access Relaying Techniques with Imperfect Source-Relay Links [PDF]

open access: yes, 2014
An outage probability that is independent of signaling schemes is theoretically derived in this paper for an orthogonal multiple-access relay channel (MARC) system, where the estimates of the information sequences sent from source nodes, regardless of ...

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma

open access: yesMolecular Oncology, EarlyView.
Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

Fractionally Spread Multicarrier CDMA: A Multiple-Access Scheme for Various Wireless Channels [PDF]

open access: yes, 2003
In multicarrier code-division multiple-access (MCCDMA) the total system bandwidth is divided into a number of subbands, where each subband may use direct-sequence (DS) spreading and each subband signal is transmitted using a subcarrier frequency. In this

Astrocyte heterogeneity in brain metastases

open access: yesMolecular Oncology, EarlyView.
Astrocytes emerge as pivotal regulators of metastatic colonization, survival, immune remodeling, and therapy response associated with an increasing heterogeneity that requires spatially and longitudinally resolved approaches to uncover regulatory programs and guide context‐specific therapies.

Performance of Generalized Multicarrier DS-CDMA over Nakagami-$m$ Fading Channels [PDF]

open access: yes, 2002
A class of generalized multicarrier direct sequence code-division multiple-access (MC DS-CDMA) schemes is defined and its performance is considered over multipath Nakagamifading channels. The spacing between two adjacent subcarriers of the generalized MC

Non-Orthogonal Multiple Access for Next-Generation Satellite Systems: Flexibility Exploitation and Resource Optimization [PDF]

open access: yes, 2022
In conventional satellite communication systems, onboard resource management follows pre-design approaches with limited flexibility. On the one hand, this can simplify the satellite payload design.

Joint time and beam domain non-orthogonal multiple access

open access: yesTongxin xuebao, 2021
In order to improve the system’s ability to accommodate connected devices, a joint time and beam domain non-orthogonal multiple access (NOMA) scheme was proposed, which was suitable for millimeter wave massive multiple-input multiple-output (MIMO ...

Wireless-Powered Communications With Non-Orthogonal Multiple Access [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2016
We study a wireless-powered uplink communication system with non-orthogonal multiple access (NOMA), consisting of one base station and multiple energy harvesting users. More specifically, we focus on the individual data rate optimization and fairness improvement and we show that the formulated problems can be optimally and efficiently solved by either ...
