Fundamental limits in sensitivity minimization: multiple-input-multiple-output (MIMO) plants

IEEE Transactions on Automatic Control, 2001
The paper deals with the problem of the smallest achievable \(H_{\infty}\) norm of various weighted sensitivity functions subject to internal closed-loop stability. These values represent fundamental limits because they are the best achievable under a minimal requirement of stability.

Multiple-input multiple-output (MIMO) receiver for wideband space-time communications

12th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications. PIMRC 2001. Proceedings (Cat. No.01TH8598), 2002
A new receiver structure able to deliver high data rates in a multiple-input multiple-output (MIMO) frequency selective wireless environment is proposed and investigated. The optimal solution for the finite length MIMO decision feedback equalizer (DFE) with cancellation is derived and used to illustrate the potential of this architecture for space-time

Mutual Information of Multiple-Input Multiple-Output (MIMO) Transmission Schemes

International Journal of Wireless Information Networks, 2005
We analyze the mutual information of some common multiple-input multiple-output (MIMO) transmission schemes. Whereas most capacity evaluations are done under the assumption of Gaussian transmit symbols, we take into account restrictions on the transmit symbol alphabet and analyze real world signal constellations.

A theory of multiple-input/multiple-output (MIMO) system for mobile radio communications

12th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications. PIMRC 2001. Proceedings (Cat. No.01TH8598), 2002
Using n-element arrays for transmission and reception in a radio communication link is one of the recent focuses in wireless communication research. Most of the studies are based on the assumption that the transmitter is in complete ignorance of the channel information.

Multiple-Input Multiple-Output (MIMO) Antenna Systems

2004
Since the late 1990’s MIMO (Multiple-Input Multiple-Output) antenna systems are the subject of the enormous interest among engineers and researchers. The reason is that the theoretical capacity offered by these systems significantly exceeds the Shannon bound.

Multiple input multiple output (MIMO) radio channel models

Third International Conference on 3G Mobile Communication Technologies, 2002
In this paper we present a geometrically based stochastic model implementation of a MIMO radio channel model. This is based on a 3D two bounce model. The model is designed to be dependent on parameters associated with the deployment scenario rather than being based on any stochastic radio channel information.

Dielectric Resonator-Based Multiple-Input Multiple-Output (MIMO) Antennas

2020
This chapter discusses dielectric resonator antenna (DRA)-based multiple-input multiple-output (MIMO) antenna systems for various wireless applications with several antenna examples. A DRA supports several unique features, which makes it different from other radiating structures. The antenna acts as a backbone of a wireless communication system.
