Multiple-input multiple-output (MIMO) technology constitutes a breakthrough in the design of wireless communication systems, and is already at the core of several wireless standards. Exploiting multi-path scattering, MIMO techniques deliver significant performance enhancements in terms of data transmission rate and interference reduction. This book is a detailed introduction to the analysis and...
This paper focuses on Multiple-Input MultipleOutput (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems, where the MIMO channel order is larger than the length of the Cyclic Prefix (CP). By swapping the filtering operations of the MIMO channel and the Fast Fourier Transform (FFT), it is shown that each tone of a MIMO OFDM system can be viewed as a MIMO Single-Carrier (SC) system. A...
Multiple input multiple output (MIMO) systems using multiple transmit and receive antennas are widely recognized as the vital breakthrough that will allow future wireless systems to achieve higher data rates with limited bandwidth and power resources. The capacity of MIMO systems depends strongly on whether the channel state information (CSI) is available at the transmitter or not. The main aim...
In this thesis, different aspects of lattice-based precoding and decoding for the transmission of digital and analog data over MIMO fading channels are investigated: 1) Lattice-based precoding in MIMO broadcast systems: A new viewpoint for adopting the lattice reduction in communication over MIMO broadcast channels is introduced. Lattice basis reduction helps us to reduce the average transmitte...
Multiple-input multiple-output (MIMO) transmission is attracting interest for increasing the transmission rates of wireless systems. This paper surveys MIMO transmission technology from the viewpoints of transmission methods, access control schemes, and total transmission efficiency. We consider wireless local area networks (WLAN) systems that use MIMO technology; moreover, we focus on multiuse...

-MIMO-OFDM system has been currently recognized as one of the most competitive technology for 4G mobile wireless systems. MIMOOFDM system can compensate for the lacks of MIMO systems and give play to the advantages of OFDM system. In this paper, a general orthogonal space time block code (OSTBC) structure is proposed for multiple-input multiple-output–orthogonal frequency-division multiplexing ...
During recent years, MIMO communication systems become an important research and development subject. Many papers are already published in the fields of channel capacity, synchronization, space time coding, etc. The idea of this book was born during the Wicom Conference in 2007, where many sessions have dedicated to MIMO systems, dealing with physical channel layer as well as protocol aware MIM...
In this paper, operator based robust nonlinear control system design for multi-input multi-output nonlinear feedback control systems is proposed, that is, robust stability of the MIMO systems is studied by using operator based robust right coprime factorization approach. Some sufficient conditions for the MIMO nonlinear systems to be robust stable are derived. As a result, robust nonlinear cont...
