The development of realistic channel models that can efficiently and accurately describe a wireless propagation channel is a key research area. In this study, a generalised three-dimensional (3D) scattering channel model for land mobile systems is proposed to simultaneously describe the angular arrival of multi-path signals in the azimuth and elevation planes. The model considers a base station located...
One of the fundamental research areas in wireless communications is the development of realistic models that can efficiently and accurately describe the wireless propagation channel. In this paper, the authors developed an asymmetric geometrical-based statistical channel model for mobile system and investigated the multiple-input and multiple-output (MIMO) receiving performance. This work was first...
Multiple input multiple output (MIMO) communication architecture has spectral efficiencies far beyond those offered by conventional techniques, and is greatly to increase the channel capacity. In this paper, we investigate the MIMO channel capacity in correlated channels using the uniform angular distribution, numerical simulations are performed with Matlab to verify the proposed formula. We prove...
Multiple antenna systems are promising architectures for overcoming the effects of multi-path interference and increasing the spectrum efficiency. Capacity increases promised by MIMO systems mostly depend on the spatial correlation properties of the radio channels.

Adaptive channel tracking algorithms are studied based on LMS and KALMAN in MIMO-OFDM system. A novel adaptive channel tracking algorithm, which combines the LMS and KALMAN filter to make use of the stabilization of LMS and the accuracy of KALMAN filter, is proposed. On the one side, the algorithm can track and estimate the channel with the optimal MSE, and on the other hand, the algorithm conquers...
The researches about conditions of the resource allocation algorithm in wireless communication have been done a lot recently. An evaluation model for the adaptive algorithm of MIMO-OFDM system is built in this paper. After formulating system efficiency under static and adaptive conditions, the effect of imperfect channel state information (CSI) to MIMO-OFDM system is analyzed. Analytical and numerical...
Spatial correlation is one of the impairments in multiple- input multiple-output (MIMO) wireless communication systems. Capacity increases promised by MIMO systems mostly depend on the spatial correlation properties of the radio channels. This letter investigates the connection between these properties and the channel capacity. An analytical formula is derived for the fading correlation function of...
Spatial correlation is one of the impairments practical multiple-input multiple-output (MIMO) wireless communication systems have to be coped with. Capacity increases promised by MIMO systems mostly depend on the spatial correlation properties of the radio channels. This paper investigates the connection between these properties and the channel capacity. By investigating the channel capacity using...
