This paper proposes a novel three-dimensional (3D) regular-shaped geometry-based stochastic model (RS-GBSM) for non-isotropic multiple-input multiple-output (MIMO) mobile-to-mobile (M2M) Ricean fading channels. The proposed model, combining a two-sphere model and an elliptic-cylinder model, is the first 3D RS-GBSM that has the ability to investigate the impact of the vehicular traffic density (VTD)...
Multiple-input multiple-output (MIMO) technology using orthogonal frequency division multiplexing (OFDM) together called MIMO-OFDM has emerged as the viable alterative to meet the demands of greater bandwidth and quality of service of the ever expanding mobile communication networks. For MIMO-OFDM systems channel estimation is one of the challenging issues. Statistical characteristics of wireless...
From the beginnings of mobile communication, there is a high demand for realistic models for mobile fading channels. The reason for the demand is that channel models are essential for the performance evaluation, parameter optimisation, and test of mobile communication systems. Design methods for mobile fading channels are therefore of great importance for system engineers who are involved in the development...
Recently, orthogonal frequency division multiplexing (OFDM) has become a popular technique for transmission of signals over wireless channels. Also, multiple-input multiple-output (MIMO) is one of the most promising technologies for assisting fading and improving link reliability without sacrificing bandwidth efficiency. The combination of OFDM and MIMO seems to be the key technology in next generation...
