Low-Complexity Multi-Antenna Coded Caching Using Location-Aware Placement Delivery Arrays
Hamidreza Bakhshzad Mahmoodi, MohammadJavad Salehi, Antti Tolli
A location-aware multi-antenna coded caching scheme is proposed for applications with location-dependent data requests, such as wireless immersive experience, where users are immer…
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…
Low-Subpacketization Multi-Antenna Coded Caching for Dynamic Networks
MohammadJavad Salehi, Emanuele Parrinello, Hamidreza Bakhshzad Mahmoodi +1
Multi-antenna coded caching combines a global caching gain, proportional to the total cache size in the network, with an additional spatial multiplexing gain that stems from multip…
A Low-Subpacketization High-Performance MIMO Coded Caching Scheme
MohammadJavad Salehi, Hamidreza Bakhshzad Mahmoodi, Antti Tölli
In this paper, we study how coded caching can be efficiently applied to multiple-input multiple-output (MIMO) communications. This is an extension to cache-aided multiple-input sin…
Low-complexity Multicast Beamforming for Multi-stream Multi-group Communications
Hamidreza Bakhshzad Mahmoodi, Bikshapathi Gouda, MohammadJavad Salehi +1
In this paper, assuming multi-antenna transmitter and receivers, we consider multicast beamformer design for the weighted max-min-fairness (WMMF) problem in a multi-stream multi-gr…
Non-Symmetric Coded Caching for Location-Dependent Content Delivery
Hamidreza Bakhshzad Mahmoodi, MohammadJavad Salehi, Antti Tölli
Immersive viewing is emerging as the next interface evolution for human-computer interaction. A truly wireless immersive application necessitates immense data delivery with ultra-l…
D2D Assisted Multi-antenna Coded Caching
Hamidreza Bakhshzad Mahmoodi, Jarkko Kaleva, Seyed Pooya Shariatpanahi +1
A device-to-device (D2D) aided multi-antenna coded caching scheme is proposed to improve the average delivery rate and reduce the downlink (DL) beamforming complexity.} Novel beamf…
D2D Assisted Beamforming for Coded Caching
Hamidreza Bakhshzad Mahmoodi, Jarkko Kaleva, Seyed Pooya Shariatpanahi +2
Device-to-device (D2D) aided beamforming for coded caching is considered in finite signal-to-noise ratio regime. A novel beamforming scheme is proposed where the local cache conten…
