On the Capacity Regions of Two-Way Diamond Channels
Mehdi Ashraphijuo, Vaneet Aggarwal, Xiaodong Wang
In this paper, we study the capacity regions of two-way diamond channels. We show that for a linear deterministic model the capacity of the diamond channel in each direction can be…
Multiuser Joint Energy-Bandwidth Allocation with Energy Harvesting - Part II: Multiple Broadcast Channels & Proportional Fairness
Zhe Wang, Vaneet Aggarwal, Xiaodong Wang
In this paper, we consider the energy-bandwidth allocation for a network with multiple broadcast channels, where the transmitters access the network orthogonally on the assigned fr…
Multiuser Joint Energy-Bandwidth Allocation with Energy Harvesting - Part I: Optimum Algorithm & Multiple Point-to-Point Channels
Zhe Wang, Vaneet Aggarwal, Xiaodong Wang
In this paper, we develop optimal energy-bandwidth allocation algorithms in fading channels for multiple energy harvesting transmitters, each may communicate with multiple receiver…
Layered, Exact-Repair Regenerating Codes Via Embedded Error Correction and Block Designs
Chao Tian, Birenjith Sasidharan, Vaneet Aggarwal +2
A new class of exact-repair regenerating codes is constructed by stitching together shorter erasure correction codes, where the stitching pattern can be viewed as block designs. Th…
Joint Latency and Cost Optimization for Erasure-coded Data Center Storage
Yu Xiang, Tian Lan, Vaneet Aggarwal +1
Modern distributed storage systems offer large capacity to satisfy the exponentially increasing need of storage space. They often use erasure codes to protect against disk and node…
On the Symmetric -user Interference Channels with Limited Feedback
Mehdi Ashraphijuo, Vaneet Aggarwal, Xiaodong Wang
In this paper, we develop achievability schemes for symmetric -user interference channels with a rate-limited feedback from each receiver to the corresponding transmitter. We st…
