Rate-Splitting for Overloaded Multigroup Multicast: Error Performance Evaluation
2020 IEEE International Conference on Communications Workshops (ICC Workshops), 2020 In this work, we provide the first attempt to evaluate error performance of Rate-Splitting (RS) based transmission strategies with constellation-constrained coding/modulation. The consider scenario is an overloaded multigroup multicast, where RS can mitigate the inter-group interference thus achieve a better max-min fair group rate over conventional ...

A Survey on Multipacket Reception for Wireless Random Access Networks
Journal of Computer Networks and Communications, Volume 2012, Issue 1, 2012., 2012 Multipacket reception (MPR) is the capability of simultaneous decoding of more than one packet from multiple concurrent transmissions. Continuous investigations on increasing the reception capability are giving new scientific contributions. In this paper, we provide an overview of MPR‐related research work covering (1) the theoretically proved impacts ...

Max-Min Fairness for Multicast Multigroup Multicell Transmission under Backhaul Constraints [PDF]
2016 IEEE Global Communications Conference (GLOBECOM), 2016 We consider multicell downlink transmission where multi-antenna base stations (BSs) collaborate in transferring data to multiple cochannel multicast groups. Our aim is to design a joint transmitter selection and cooperative precoding scheme which maximizes the minimum received data rate among all receivers under constraints on the individual BS ...

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 17-33, January/February 2026.In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

Dynamic Placement of Pinching Antennas for Multicast MU-MISO Downlinks
IEEE Open Journal of the Communications SocietyWithin the surface-wave communication paradigm, pinching-antenna systems employ dielectric waveguides as both transmission media and reconfigurable radiators, enabling dynamic antenna repositioning to mitigate path-loss limitations inherent in static ...

Coordinated Multicasting with Opportunistic User Selection in Multicell Wireless Systems
, 2015 Physical layer multicasting with opportunistic user selection (OUS) is examined for multicell multi-antenna wireless systems. By adopting a two-layer encoding scheme, a rate-adaptive channel code is applied in each fading block to enable successful ...
