Multiuser Diversity Gain in Cognitive Networks [PDF]
IEEE/ACM Transactions on Networking, 2010 Dynamic allocation of resources to the \emph{best} link in large multiuser networks offers considerable improvement in spectral efficiency. This gain, often referred to as \emph{multiuser diversity gain}, can be cast as double-logarithmic growth of the network throughput with the number of users.

EURASIP Journal on Wireless Communications and Networking, 2009 Multihop relay channels use multiple relay stages, each with multiple relay nodes, to facilitate communication between a source and destination. Previously, distributed space-time codes were proposed to maximize the achievable diversity-multiplexing ...

Diversity-multiplexing gain tradeoff: A tool in algebra? [PDF]
2011 IEEE Information Theory Workshop, 2011 Since the invention of space-time coding numerous algebraic methods have been applied in code design. In particular algebraic number theory and central simple algebras have been on the forefront of the research. In this paper we are turning the table and asking whether information theory can be used as a tool in algebra.

Subblocks Set Design Aided Orthogonal Frequency Division Multiplexing With All Index Modulation
IEEE Access, 2019 In recent years, OFDM with index modulation (OFDM-IM) has become a potential technique due to its improvement of diversity gain. In typical OFDM-IM schemes, incoming information bits are divided into two parts, symbols bits, and index bits.

Compact Eight-Element MIMO Antenna with Reduced Mutual Coupling and Beam-Scanning Performance
Sensors, 2022 In this study, a multiple-input multiple-output (MIMO) antenna for wide scanning is designed. By adding slits to the patches, each element is intended to strengthen the isolation between the radiating elements.
