Bearing similarity to random noise, frequency-modulated chaos signal have advantages in terms of measure accuracy, target detection capability and electromagnetic compatibility. Besides, it's easy to produce, duplicate and apply. On basis of mathematical modeling of discrete chaos mapping, this paper analyzes three types of frequency-modulated chaos signals. The Autocorrelation Function, Power Spectrum...
In this paper, a wideband multiple-input multiple-output (MIMO) simulation model for vehicle-to-vehicle (V2V) channels in T-junction propagation environments is proposed. This simulation model takes the exact relationship between the angle-of-arrival (AOA) and the angle-of-departure (AOD) into account. In order to determine the parameters of the simulation model, the Riemann sum method (RSM) is applied...
In this paper, we propose a high-performance simulation model for wideband multiple-input multiple-output (MIMO) vehicle-to-vehicle (V2V) fading channels in T-junction propagation environments. The so-called Riemann sum method (RSM) is applied for the parametrisation of the simulation model. Furthermore, the statistical properties of the wideband MIMO V2V channel simulation model, such as the space-time-frequency...
CYP4F2 is a member of the cytochrome P450 enzymes and is responsible for metabolizing arachidonic acid to 20-hydroxyeicosatetraenoic acid (20-HETE); 20-HETE plays a role in the regulation of vascular tone in the cerebral, coronary, and renal circulation. The present study aimed to evaluate whether or not the CYP4F2 gene polymorphism V433M (rs2108622) is involved in ischemic stroke in the Northern...
In this paper, a novel isotropic scatter distribution wideband fading channel model for MIMO mobile-to-mobile (M2M) is proposed. The starting point for the derivation of the model is a new T-intersection geometric street scattering model, where both single-, double-bounced scattering mechanisms are assumed. Our geometry-based channel model takes into account the exact relationship between angle of...
In this paper, a new wideband multiple-input multiple-output (MIMO) fading channel model for vehicle-to-vehicle (V2V) communications is proposed. The MIMO V2V channel model, called for brevity T-model, captures the propagation effects that occur if vehicles move towards a junction with a side road and corner buildings. The starting point for the derivation of the T-model is a new geometric T-junction...
In future, cars will form a network with other cars and roadside data systems to exchange information that alerts the driver on traffic congestion, road conditions, and accidents. It is expected that vehicle-to-vehicle communication systems will play an important role in intelligent transportation systems. MIMO systems employ multiple transmit and multiple receive antennas, combined with the opportunities...

In this paper, we propose a geometrical two-erose-ring scattering model under the assumption that both the transmitter and the receiver are moving. Derived from this model, a multiple-input-multiple-output (MIMO) mobile-to-mobile channel model is given. Here, we focus on the reference model, which is based on the assumption that the transmitter and the receiver are surrounded by an infinite number...
Recently there are many different approaches to the modeling and simulation of mobile radio fading channels. In this paper, tow kinds of improved Jakes' simulators for Rayleigh fading channels are introduced and the second-order statistics of these improved Jakes' simulator are analyzed. On comparison of some importance statistical properties of the classical Jakes' simulator, it is proved that the...
