Hybrid ARQ in Multiple-Antenna Slow Fading Channels: Performance Limits and Optimal Linear Dispersion Code Design
Cong Shen, Michael P. Fitz
This paper focuses on studying the fundamental performance limits and linear dispersion code design for the MIMO-ARQ slow fading channel. Optimal average rate of well-known HARQ pr…
Opportunistic Spatial Orthogonalization and Its Application in Fading Cognitive Radio Networks
Cong Shen, Michael P. Fitz
Opportunistic Spatial Orthogonalization (OSO) is a cognitive radio scheme that allows the existence of secondary users and hence increases the system throughput, even if the primar…
Untangling the SVD's of Random Matrix Sample Paths
D. W. Browne, M. W. Browne, M. P. Fitz
Singular Value Decomposition (SVD) is a powerful tool for multivariate analysis. However, independent computation of the SVD for each sample taken from a bandlimited matrix random…
On Reduced Complexity Soft-Output MIMO ML detection
Massimiliano Siti, Michael P. Fitz
In multiple-input multiple-output (MIMO) fading channels maximum likelihood (ML) detection is desirable to achieve high performance, but its complexity grows exponentially with the…
Experiments with Compact Antenna Arrays for MIMO Radio Communications
D. W. Browne, M. Manteghi, M. P. Fitz +1
The problem addressed in this study is how to design and test compact antenna arrays for portable Mulitple-Input Multiple-Output (MIMO) transceivers. Mutual coupling in an antenna…
Layered Orthogonal Lattice Detector for Two Transmit Antenna Communications
Massimiliano Siti, Michael P. Fitz
A novel detector for multiple-input multiple-output (MIMO) communications is presented. The algorithm belongs to the class of the lattice detectors, i.e. it finds a reduced complex…
