This paper investigates the applicability of multiple-input multiple-output (MIMO) technology to satellite communications at the Ku-band and above. After introducing the possible diversity sources to form a MIMO matrix channel in a satellite environment, particular emphasis is put on satellite diversity. Two specific different topics from the field of MIMO technology applications to satellite c...

With the integration of Internet and multimedia applications in next generation wireless communications, the demand for wide-band high data rate communication services is growing. In recent years, multiple transmitter and receiver antennas are employed in the wireless communications systems to adapt various demands of high speed wireless links and improved signal to noise ratio . In order to ta...

Description: Multiple-input multiple-output (MIMO) channels provide an abstract and unified representation of different physical communication systems, ranging from multi-antenna wireless channels to wireless digital subscriber line (DSL) systems. They have the key property that several data streams can be simultaneously established. MIMO Transceiver Design via Majorization Theory presents an u...

— The paper is concerned with the application of probability theory to Multi-Input Multi-Output (MIMO) transmission systems. We provide a theoretical formula to compute the error rate in such systems. Furthermore, analysis of this formula shows that simulation results are not reliable at high SNR. Finally, we provide an expression to compute the relative precision of the simulation results. Thi...

This paper investigates the performance of multiple-input multiple-out (MIMO) wireless communication systems in a multiuser environment. The user information is defined by a data matrix generated by the observed input-output data of the system, from which subspace identification method is developed using LQ-decomposition of the matrix. The LQ-decomposition is basically used to solve for the use...

the lane change maneuver is among the most popular driving behaviors. it is also the basic element of important maneuvers like overtaking maneuver. therefore, it is chosen as the focus of this study and novel multi-input multi-output adaptive neuro-fuzzy inference system models (manfis) are proposed for this behavior. these models are able to simulate and predict the future behavior of a driver...

Blind channel estimation for periodic sequence DS-CDMA systems can be cast into the framework of ”structured” blind estimation of multi-input / multi-output (MIMO) FIR systems, where the structure is imposed by the user’s signatures. A possible approach to tackle this problem consists in looking for a structured solution to one of the so-called ”blind” MIMO-FIR system identification techniques ...

Interaction phenomenon in multi-input multi-output (MIMO) systems is an essential difficulty of controllers planning. To design the appropriate controller in multivariable systems, the interaction in the system must be measured. The theories for planning decouplers are valid only for minimum-phase systems. Nevertheless, the most of physical systems are non-minimum phase. In this paper a new ide...

Massive multiple-input-multiple-output (MIMO) systems use few hundred antennas to simultaneously serve large number of wireless broadband terminals. It has been incorporated into standards like long term evolution (LTE) and IEEE802.11 (Wi-Fi). Basically, the more the antennas, the better shall be the performance. Massive MIMO systems envision accurate beamforming and decoding with simpler and p...

This work studies the performance of our recently proposed differential feedback scheme for multi-input-multi-output (MIMO) communication systems using real channel measurement data. The algorithm is applied to the channel correlation matrix exploiting geodesic curves and the intrinsic geometry of positive definite Hermitian matrices. The performance of this and a conventional non-differential ...
