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) radar: performance issues

Conference Record of the Thirty-Eighth Asilomar Conference on Signals, Systems and Computers, 2004., 2005
The application of multiple-input multiple-output (MIMO) techniques to multistage radar offers a number of advantages, including improved resolution and sensitivity. Depending upon the radar's mode of operation, the array design and the environment, these advantages may or may not be significant. In this paper, a simple analytic model for ground moving

Multiple-input multiple-output (MIMO) radio channel measurements

Vehicular Technology Conference Fall 2000. IEEE VTS Fall VTC2000. 52nd Vehicular Technology Conference (Cat. No.00CH37152), 2002
We present results from the first field test to characterize the mobile multiple-input multiple-output (MIMO) radio channel. We measured the capacity normalized to a single antenna system, and fading correlation between antennas of a system with 4 antennas on a laptop computer and 4 antennas at a rooftop base station.

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

Using Waste Factor to Optimize Energy Efficiency in Multiple-Input Single-Output (MISO) and Multiple-Input Multiple-Output (MIMO) Systems

GLOBECOM 2024 - 2024 IEEE Global Communications Conference
This paper introduces Waste Factor (W) and Waste Figure (WF) to assess power efficiency in any multiple-input multiple-output (MIMO) or single-input multiple-output (SIMO) or multiple-input single-output (MISO) cascaded communication system. This paper builds upon the new theory of Waste Factor, which systematically models added wasted power in any ...

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.

Decoupling MIMO systems with multiple input/output time delays

2010 11th International Conference on Control Automation Robotics & Vision, 2010
Decoupling multi-input multi-output systems is a simplifying technique to design, implement and tune control systems. If there are also multiple delays, the decoupling is even more interesting although there is always a prize to pay and the resulting controllers can become excessively complex.
