In this paper, a novel orthogonal frequency division multiplexing (OFDM) modulation scheme based on discrete Hartley transform (DHT) combined with optical spatial modulation (OSM) is proposed for visible light communication (VLC) systems. In the proposed scheme, the function of the conventional discrete Fourier transform (DFT) is fulfilled by the DHT and real constellation schemes such as binary phase...
In order to describe the highly scattered property of millimeter wave (mmWave) multiple-input multiple-output (MIMO) channels, the existing high resolution frequency domain space-alternating generalized expectation-maximization (FD-SAGE) algorithm is studied and extended to three-dimentional (3D) MIMO case by including the estimation of elevation angles. The signal model and estimation procedure are...
This paper first proposes a three dimensional (3-D) non-stationary wideband multi-confocal ellipsoid channel model with uniform planar antenna array (UPA) for massive multiple-input multiple-output (MIMO) wireless communication systems. The proposed 3-D geometry-based stochastic model (GBSM) not only considers the non-stationary channel characteristics in time domain but also describes the non-stationary...
To mitigate the small-scale fading of the backscatter RFID channel, this paper presents a new signaling scheme for multiple-antenna RF tag. The scheme is based on high data rate (HDR) Alamouti code from field extension, which has better coding gain than conventional Alamouti space-time block codes (STBC). Simulation results show the performance advantage of the new signaling scheme over the previously...
A boiler-turbine unit is a typical multi-input multi-output (MIMO) industrial control system in power plant, which has nonlinear and couple characteristics. As there exist strong couplings between main steam pressure and power output, we present a new coordinated control strategy: ath-order inverse system method based on Support Vector Machine (SVM). Cascading SVM inversion with the original system...
This paper is concerned with the stability analysis for a class of MIMO networked control systems (NCSs) with network constraints. In view of MIMO NCSs where network is of limited access channels, a discrete-time switched delay model is formulated. By constructing a novel piecewise Lyapunov-Krasovskii functional, a new stability criterion is developed in terms of linear matrix inequalities. A numerical...
In this paper we describe a multiple-input multipleoutput (MIMO) communication testbed, in which real-time signal processing is achieved with the help of Sundance's digital signal processing platform including TI DSP modules, XINLINX FPGA modules and A/D & D/A modules. As an advanced wireless communication system, the presented MIMO testbed not only provides a real communication link for theoretical...
