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…
Resource Allocation for Power Minimization in the Downlink of THP-based Spatial Multiplexing MIMO-OFDMA Systems
Marco Moretti, Luca Sanguinetti, Xiaodong Wang
In this work, we deal with resource allocation in the downlink of spatial multiplexing MIMO-OFDMA systems. In particular, we concentrate on the problem of jointly optimizing the tr…
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…
Sequential Joint Spectrum Sensing and Channel Estimation for Dynamic Spectrum Access
Yasin Yilmaz, Ziyu Guo, Xiaodong Wang
Dynamic spectrum access under channel uncertainties is considered. With the goal of maximizing the secondary user (SU) throughput subject to constraints on the primary user (PU) ou…
Power Allocation for Energy Harvesting Transmitter with Causal Information
Zhe Wang, Vaneet Aggarwal, Xiaodong Wang
We consider power allocation for an access-controlled transmitter with energy harvesting capability based on causal observations of the channel fading state. We assume that the sys…
Iterative Dynamic Water-filling for Fading Multiple-Access Channels with Energy Harvesting
Zhe Wang, Vaneet Aggarwal, Xiaodong Wang
In this paper, we develop optimal energy scheduling algorithms for -user fading multiple-access channels with energy harvesting to maximize the channel sum-rate, assuming that t…
