Joint Unitary Triangularization for MIMO Networks
Joint Unitary Triangularization MIMO Networks
2011/2/24
This work considers communication networks where
individual links can be described as MIMO channels. Unlike orthogonal modulation methods (such as the singular-value decomposition),we allow interfere...
Compressed Sensing for Feedback Reduction in MIMO Broadcast Channels
Compressed Feedback Reduction MIMO Broadcast Channels
2011/2/28
We propose a generalized feedback model and compressive sensing based opportunistic feedback
schemes for feedback resource reduction in MIMO Broadcast Channels under the assumption that both uplink a...
Pair-wise Markov Random Fields Applied to the Design of Low Complexity MIMO Detectors
Pair-wise Markov Random Fields Design Low Complexity MIMO Detectors
2010/11/24
Pair-wise Markov random fields (MRF) are considered for application to the development of low complexity, iterative MIMO detection. Specifically, we consider two types of MRF, namely, the fully-conne...
Interference Alignment Through User Cooperation for Two-cell MIMO Interfering Broadcast Channels
Two-cell MIMO Interfering Broadcast Channels
2010/11/22
This paper focuses on two-cell multiple-input multiple-output (MIMO) Gaussian interfering broadcast channels (MIMO-IFBC) with $K$ cooperating users on the cell-boundary of each BS. It corresponds to a...
Degrees of Freedom Regions of Two-User MIMO Z and Full Interference Channels: The Benefit of Reconfigurable Antennas
Degrees of Freedom Regions Two-User MIMO Z Full Interference Channels
2010/11/15
We study the degrees of freedom (DoF) regions of two-user multiple-input multiple-output (MIMO) Z and full interference channels in this paper. We assume that the receivers always have perfect channel...
