This book chapter reviews signal detection and parameter estimation techniques for multiuser multiple-antenna wireless systems with a very large number of antennas, known as massive multi-input multi-output (MIMO) systems. We consider both centralized antenna systems (CAS) and distributed antenna systems (DAS) architectures in which a large number of antenna elements are employed and focus on t...

This paper addresses the disturbance decoupling problem (DDP) for nonlinear systems, extending the results for continuous-time systems into the discrete-time case. Sufficient conditions are given for the solvability of the problem. The notion of the rank of a one-form is used to find the static measurement feedback that solves the DDP whenever possible. Moreover, necessary and sufficient condit...

The author has developed a novel approach to fuzzy modeling from input–output data. Using the basic techniques of soft computing, the method allows supervised approximation of multi-input multi-output (MIMO) systems. Typically, a small number of rules are produced. The learning capacity of FuGeNeSys is considerable, as is shown by the numerous applications developed. The paper gives a significa...

An observer design based on backstepping approach for a class of state affine systems is proposed. This class of nonlinear systems is determined via a constructive algorithm applied to a general nonlinear Multi Input-Multi Output systems. Some examples are given in order to illustrate the proposed methodology.

This paper examines the diversity technique of receivers in convolutionally encoded MIMO (Multi-Input Multi-Output) systems. We have proposed W-EP (Weighting-by Eigenvalue Power) soft-decision decoder in 2x2 encoded MIMO systems, confirmed that the weighting factor based on the eigenvalue of channel matrix has a significant effect on BER (Bit Error Rate) performances [1]. On the other hand, lar...
