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 ...

Fundamental Limits of Caching [PDF]
, 2014 Caching is a technique to reduce peak traffic rates by prefetching popular content into memories at the end users. Conventionally, these memories are used to deliver requested content in part from a locally cached copy rather than through the network ...

IEEE Photonics Journal, 2012 We demonstrate a technique to simultaneously generate multiple delayed signals through four-wave mixing (FWM) wavelength multicasting in a single-pump stimulated Brillouin scattering (SBS)-based slow-light system. The signal delay is achieved with an SBS

On the Empirical Evaluation of Multicasting with Minimum Delay Variation [PDF]
International Journal of Networked and Distributed Computing (IJNDC), 2016 In certain types of Internet applications, multicasting with Quality of Service (QoS) optimizations are required on both the end-to-end delay from the source to the destinations, as well as the difference in the end-to-end delay between the destinations.

Rate-Splitting for Max-Min Fair Multigroup Multicast Beamforming in Overloaded Systems [PDF]
, 2017 In this paper, we consider the problem of achieving max-min fairness amongst multiple co-channel multicast groups through transmit beamforming. We explicitly focus on overloaded scenarios in which the number of transmitting antennas is insufficient to ...

Multicast snooping: a new coherence method using a multicast address network [PDF]
Proceedings of the 26th International Symposium on Computer Architecture (Cat. No.99CB36367), 1999 This paper proposes a new coherence method called "multicast snooping" that dynamically adapts between broadcast snooping and a directory protocol. Multicast snooping is unique because processors predict which caches should snoop each coherence transaction by specifying a multicast "mask." Transactions are delivered

Throughput Bound of XOR Coded Wireless Multicasting to Three Clients
, 2015 It is a well-known result that constructing codewords over $GF(2)$ to minimize the number of transmissions for a single-hop wireless multicasting is an NP-complete problem. Linearly independent codewords can be constructed in polynomial time for all the $

3D As‐Built Environments in Extended Reality Applications: A Systematic Review
The Photogrammetric Record, Volume 41, Issue 194, April/June 2026.This systematic review identifies BIM and game engines as the primary tools for integrating 3D as‐built environments into XR. While multi‐sensor fusion and multimodal interaction enhance immersion, persistent challenges like manual modeling and bandwidth limitations continue to hinder full ecosystem maturation.

Weighted Fair Multicast Multigroup Beamforming under Per-antenna Power Constraints [PDF]
, 2014 A multi-antenna transmitter that conveys independent sets of common data to distinct groups of users is considered. This model is known as physical layer multicasting to multiple co-channel groups.
