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…
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…
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…
Antenna array geometry and coding performance
Weijun Zhu, Heechoon Lee, Daniel Liu +1
This paper provides details about experiments in realistic, urban, and frequency flat channels with space-time coding that specifically examines the impact of the number of receive…
