Transmission and Scheduling Aspects of Distributed Storage and Their Connections with Index Coding
Parastoo Sadeghi
Index coding is often studied with the assumption that a single source has all the messages requested by the receivers. We refer to this as \emph{centralized} index coding. In cont…
Multi-Cell Multiuser Massive MIMO Networks: User Capacity Analysis and Pilot Design
Noman Akbar, Nan Yang, Parastoo Sadeghi +1
We propose a novel pilot sequence design to mitigate pilot contamination in multi-cell multiuser massive multiple-input multiple-output networks. Our proposed design generates pilo…
A Game-theoretic Perspective on Communication for Omniscience
Ni Ding, Chung Chan, Tie Liu +2
We propose a coalition game model for the problem of communication for omniscience (CO). In this game model, the core contains all achievable rate vectors for CO with sum-rate bein…
Performance Characterization and Transmission Schemes for Instantly Decodable Network Coding in Wireless Broadcast
Mingchao Yu, Parastoo Sadeghi, Neda Aboutorab
We consider broadcasting a block of packets to multiple wireless receivers under random packet erasures using instantly decodable network coding (IDNC). The sender first broadcasts…
The Benefit of Limited Feedback to Generation-Based Random Linear Network Coding in Wireless Broadcast
Mingchao Yu, Parastoo Sadeghi, Alex Sprintson
Random linear network coding (RLNC) is asymptotically throughput optimal in the wireless broadcast of a block of packets from a sender to a set of receivers, but suffers from heavy…
Instantly Decodable Network Coding for Real-Time Scalable Video Broadcast over Wireless Networks
Mohammad S. Karim, Parastoo Sadeghi, Sameh Sorour +1
In this paper, we study a real-time scalable video broadcast over wireless networks in instantly decodable network coded (IDNC) systems. Such real-time scalable video has a hard de…
On Minimizing the Average Packet Decoding Delay in Wireless Network Coded Broadcast
Mingchao Yu, Alex Sprintson, Parastoo Sadeghi
We consider a setting in which a sender wishes to broadcast a block of K data packets to a set of wireless receivers, where each of the receivers has a subset of the data packets a…
Fairest Constant Sum-rate Transmission for Cooperative Data Exchange: An M-convex Minimization Approach
Ni Ding, Rodney A. Kennedy, Parastoo Sadeghi
We consider the fairness in cooperative data exchange (CDE) problem among a set of wireless clients. In this system, each client initially obtains a subset of the packets. They exc…
Estimating Minimum Sum-rate for Cooperative Data Exchange
Ni Ding, Rodney A. Kennedy, Parastoo Sadeghi
This paper considers how to accurately estimate the minimum sum-rate so as to reduce the complexity of solving cooperative data exchange (CDE) problems. The CDE system contains a n…
