Sensitive White Space Detection with Spectral Covariance Sensing
Jaeweon Kim, Jeffrey G. Andrews
This paper proposes a novel, highly effective spectrum sensing algorithm for cognitive radio and whitespace applications. The proposed spectral covariance sensing (SCS) algorithm e…
Random Access Transport Capacity
Jeffrey G. Andrews, Steven Weber, Marios Kountouris +1
We develop a new metric for quantifying end-to-end throughput in multihop wireless networks, which we term random access transport capacity, since the interference model presumes u…
Adaptive Spatial Intercell Interference Cancellation in Multicell Wireless Networks
Jun Zhang, Jeffrey G. Andrews
Downlink spatial intercell interference cancellation (ICIC) is considered for mitigating other-cell interference using multiple transmit antennas. A principle question we explore i…
Multi-mode Transmission for the MIMO Broadcast Channel with Imperfect Channel State Information
Jun Zhang, Marios Kountouris, Jeffrey G. Andrews +1
This paper proposes an adaptive multi-mode transmission strategy to improve the spectral efficiency achieved in the multiple-input multiple-output (MIMO) broadcast channel with del…
Network Coding with Two-Way Relaying: Achievable Rate Regions and Diversity-Multiplexing Tradeoffs
Chun-Hung Liu, Feng Xue, Jeffrey G. Andrews
This paper addresses the fundamental characteristics of information exchange via multihop network coding over two-way relaying in a wireless ad hoc network. The end-to-end rate reg…
Coverage in Multi-Antenna Two-Tier Networks
Vikram Chandrasekhar, Marios Kountouris, Jeffrey G. Andrews
In two-tier networks -- comprising a conventional cellular network overlaid with shorter range hotspots (e.g. femtocells, distributed antennas, or wired relays) -- with universal f…
