In this paper, based on the tapped delay line (TDL) structure, we propose a geometry-based stochastic model (GBSM) for wideband multiple-input multiple-output (MIMO) mobile-to-mobile (M2M) Ricean fading channels. The proposed wideband model is the first GBSM that has the ability to study the impact of the vehicular traffic density (VTD) on channel statistics for different time delays, i.e., for every...
This paper develops a generic geometry-based stochastic model for mobile-to-mobile (M2M) Ricean fading channels. From the generic model, the level crossing rate (LCR) and average fade duration (AFD) are derived. Based on the derived expressions, we for the first time investigate the LCR and AFD for M2M channels with different vehicular traffic densities (VTDs). Excellent agreement is achieved between...
In this paper, a generic and adaptive geometrical- based stochastic reference model is proposed for multiple-input multiple-output (MIMO) mobile-to-mobile (M2M) Ricean fading channels. The proposed model employs a combined two-ring model and elliptical-ring model, where the received signal is constructed as a sum of the line-of-sight (LoS), single-, and double-bounced rays with different energies...
In this paper, a novel adaptive detection scheme for the case of multiple-input multiple-output (MIMO) Ricean channels with two transmit and receive antenna elements is presented. Our prime aim is to reduce the extensive complexity of maximum-likelihood (ML) detectors by developing an adaptive scheme which switches between a ML and a much simpler zero-forcing (ZF) detector depending on the instantaneous...
This paper proposes a new space-time-frequency (STF) correlation model based on the two-ring model with both single- and double-bounced rays for miltiple-input multiple- output (MIMO) mobile-to-mobile (M2M) multicarrier ricean fading channels in a non-isotropic scattering environment. The proposed model allows us to study the correlation functions (CFs) between any two sub-channels with different...
