Distributed Precoding Design for Multi-Group Multicasting in Cell-Free Massive MIMO
Bikshapathi Gouda, Italo Atzeni, Antti Tölli
We consider multi-group multicast precoding designs for cell-free massive multiple-input multiple-output (MIMO) systems. To optimize the transmit and receive beamforming strategies…
Multicast Beamformer Design for MIMO Coded Caching Systems
MohammadJavad Salehi, Mohammad NaseriTehrani, Antti Tölli
Coded caching (CC) techniques have been shown to be conveniently applicable in multi-input multi-output (MIMO) systems. In a -user network with spatial multiplexing gains of …
Pilot-Aided Distributed Multi-Group Multicast Precoding Design for Cell-Free Massive MIMO
Bikshapathi Gouda, Italo Atzeni, Antti Tölli
We propose fully distributed multi-group multicast precoding designs for cell-free massive multiple-input multiple-output (MIMO) systems with modest training overhead. We target th…
Multi-antenna Coded Caching at Finite-SNR: Breaking Down the Gain Structure
MohammadJavad Salehi, Antti Tölli
Multi-antenna coded caching (CC) techniques are considered viable options for achieving higher data rates in future networks, especially for the prominent use case of multimedia-dr…
Polarization Diversity-enabled LOS/NLOS Identification via Carrier Phase Measurements
Onel L. A. López, Dileep Kumar, Antti Tölli
The provision of accurate localization is an increasingly important feature of wireless networks. To this end, a reliable distinction between line-of-sight (LOS) and non-LOS (NLOS)…
Coded Caching and Spatial Multiplexing Gain Trade-off in Dynamic MISO Networks
Milad Abolpour, MohammadJavad Salehi, Antti Tolli
The global caching gain of multi-antenna coded caching techniques can be also mostly achieved in dynamic network setups, where the cache contents of users are dictated by a central…
Enhancing Next-Generation Extended Reality Applications with Coded Caching
MohammadJavad Salehi, Kari Hooli, Jari Hulkkonen +1
The next evolutionary step in human-computer interfaces will bring forward immersive digital experiences that submerge users in a 3D world while allowing them to interact with virt…
Asymmetric Coded Caching for Multi-Antenna Location-Dependent Content Delivery
Hamidreza Bakhshzad Mahmoodi, MohammadJavad Salehi, Antti Tölli
Efficient usage of in-device storage and computation capabilities are key solutions to support data-intensive applications such as immersive digital experiences. This paper propose…
