Multi-input, multi-output (MIMO) communications systems have attracted considerable attention over the past decade, mostly for single-user, point-to-point scenarios. The multipleuser MIMO case has attracted less attention, and most of the research on this problem has focused on uplink communications. Only recently has the multi-user MIMO downlink been addressed, beginning with information-theor...

Adaptive inverse control is an automatic control-system design method which “learns” over time how to control a dynamic system (“plant”). The technique may be applied to single-input single-output (SISO) and multi-input multi-output (MIMO) plants. The plant may be linear or nonlinear. A problem with adaptive inverse control in its current state is that the learning algorithms are very slow. Thi...

This paper presents a nonlinear control strategy utilizing the linearization and input-output decoupling approach for a nonlinear dynamic model of proton exchange membrane fuel cells (PEMFCs). The multiple-input single-output (MISO) nonlinear model of the PEMFC is derived first. The dynamic model is then transformed into a multiple-input multiple-output (MIMO) square system by adding additional...

In this paper modifications of intensifiers have been done for the injection into the receptive field of the fuzzy neural networks. Algorithmic developments for these modifiers are carried out for single-input single-output (SISO) as well as for multi-input multi-output (MIMO) fuzzy neural networks. This work can be beneficial for applications in different fields such as image processing, patte...

time-delay identification is one of the most important parameters in designing controllers. in the cases where the number of inputs and outputs in a system are more than one, this identification is of great concern. in this paper, a novel autocorrelation-based scheme for the state variable time-delay identification for multi-input multi-output (mimo) system has been presented. this method is ba...

The capacity performance of multi-user multiple input multiple output (MIMO) in a cellular system is of a great interest. This paper presents a comparative study on the transmit power control (TPC) schemes for uplink multi-user MIMO systems. Two kinds of TPC schemes, namely, zero-outage TPC and minimum interference TPC, are considered. The capacities of both schemes are theoretically analyzed a...

The problem of output feedback stabilizability of multi-input-multi-output (MIMO) multidimensional (n-D) linear systems is investigated using n-D polynomial matrix theory. A simple necessary and sufficient condition for output feedback stabilizability of a given MIMO n-D linear system is derived in terms of the generating polynomials associated with any matrix fraction descriptions of the syste...
