PolarDenseNet: A Deep Learning Model for CSI Feedback in MIMO Systems
Pranav Madadi, Jeongho Jeon, Joonyoung Cho +3
In multiple-input multiple-output (MIMO) systems, the high-resolution channel information (CSI) is required at the base station (BS) to ensure optimal performance, especially in th…
Relay-Assisted User Scheduling in Wireless Networks with Hybrid-ARQ
Caleb K. Lo, John J. Hasenbein, Sriram Vishwanath +1
This paper studies the problem of relay-assisted user scheduling for downlink wireless transmission. The base station or access point employs hybrid automatic-repeat-request (HARQ)…
An Energy-Based Comparison of Long-Hop and Short-Hop Routing in MIMO Networks
Caleb K. Lo, Sriram Vishwanath, Robert W. Heath
This paper considers the problem of selecting either routes that consist of long hops or routes that consist of short hops in a network of multiple-antenna nodes, where each transm…
Relay Subset Selection in Wireless Networks Using Partial Decode-and-Forward Transmission
Caleb K. Lo, Sriram Vishwanath, Robert W. Heath
This paper considers the problem of selecting a subset of nodes in a two-hop wireless network to act as relays in aiding the communication between the source-destination pair. Opti…
The Impact of Channel Feedback on Opportunistic Relay Selection for Hybrid-ARQ in Wireless Networks
Caleb K. Lo, Robert W. Heath, Sriram Vishwanath
This paper presents a decentralized relay selection protocol for a dense wireless network and describes channel feedback strategies that improve its performance. The proposed selec…
Rate Bounds for MIMO Relay Channels
Caleb K. Lo, Sriram Vishwanath, Robert W. Heath
This paper considers the multi-input multi-output (MIMO) relay channel where multiple antennas are employed by each terminal. Compared to single-input single-output (SISO) relay ch…
