Multi-point Coordination in Massive MIMO Systems with Sectorized Antennas
Shahram Shahsavari, Mehrdad Nosrati, Parisa Hassanzadeh +3
Non-cooperative cellular massive MIMO, combined with power control, is known to lead to significant improvements in per-user throughput compared with conventional LTE technology. I…
Centralized Caching and Delivery of Correlated Contents over Gaussian Broadcast Channels
Qianqian Yang, Parisa Hassanzadeh, Deniz Gündüz +1
Content delivery in a multi-user cache-aided broadcast network is studied, where a server holding a database of correlated contents communicates with the users over a Gaussian broa…
Rate-Distortion-Memory Trade-offs in Heterogeneous Caching Networks
Parisa Hassanzadeh, Antonia M. Tulino, Jaime Llorca +1
Caching at the wireless edge can be used to keep up with the increasing demand for high-definition wireless video streaming. By prefetching popular content into memory at wireless…
Rate-Memory Trade-Off for Caching and Delivery of Correlated Sources
Parisa Hassanzadeh, Antonia M. Tulino, Jaime Llorca +1
This paper studies the fundamental limits of content delivery in a cache-aided broadcast network for correlated content generated by a discrete memoryless source with arbitrary joi…
On Coding for Cache-Aided Delivery of Dynamic Correlated Content
Parisa Hassanzadeh, Antonia M. Tulino, Jaime Llorca +1
Cache-aided coded multicast leverages side information at wireless edge caches to efficiently serve multiple unicast demands via common multicast transmissions, leading to load red…
