Robust minimum variance beamforming
Ellipsoidal calculus Hadamard product robust beamforming second-order cone programming
2015/8/10
This paper introduces an extension of minimum variance beamforming, also known as Capon's method, that explicitly takes into account variation or uncertainty in the assumed array response. Sources of ...
Worst-Case Robust Multiuser Transmit Beamforming Using Semidefinite Relaxation: Duality and Implications
Worst-Case Robust Multiuser Semidefinite Relaxation Duality Implications Information Theory
2012/4/17
This paper studies a downlink multiuser transmit beamforming design under spherical channel uncertainties, using a worst-case robust formulation. This robust design problem is nonconvex. Recently, a c...
Optimal Selective Feedback Policies for Opportunistic Beamforming
Opportunistic beamforming vector broadcast channels selective feedback sum-rate majorization
2011/9/20
Abstract: This paper studies the structure of downlink sum-rate maximizing selective decentralized feedback policies for opportunistic beamforming under finite feedback constraints on the average numb...
Prescient Beamforming by Primary Transmitters in Interweave Cognitive Radio Networks with a Single Primary Receiver
Cognitive radios spectrum sensing interference mitigation beamforming dirty-paper coding
2011/9/15
Abstract: This work investigates a fundamentally novel interweave cognitive radio network where the primary transmitter takes a proactive approach towards improving the accuracy of the spectrum sensin...
Distributed Robust Multi-Cell Coordinated Beamforming with Imperfect CSI: An ADMM Approach
coordinated multi-point (CoMP) multi-cell processing beamforming robust beamforming
2011/9/1
Abstract: Multi-cell coordinated beamforming (MCBF), where multiple base stations (BSs) collaborate with each other in the beamforming design for mitigating the inter-cell interference, has been a sub...
Beamforming on the MISO interference channel with multi-user decoding capability
the MISO interference channel multi-user decoding capability Information Theory
2011/8/23
Abstract: This paper considers the multiple-input-single-output interference channel (MISO-IC) with interference decoding capability (IDC), so that the interference signal can be decoded and subtracte...
