This paper studies the optimal control of linear systems over continuous valued fading channels. The sensor measurements are sent over a fading wireless channel to a remote controller using the analog amplify and forward technique. The controller then computes a control signal, which is transmitted over another fading channel to the actuator. Under the assumption of full channel state informati...

In wireless communication systems MIMO systems are implemented to reduce the effects of multipath fading. Various fadings like Rayleigh fading, racian fading occurs in atmosphere. These fadings effect the performance of communication channel and to reduce fading various techniques are developed, one of them is diversity technique. Various diversity techniques are used to remove effects of fadin...

Abstract—We present an new method for the analytical calculation of the error probability in a Rayleigh fading channel with correlated fading amplitudes. Even though the method can be applied for more general problems, we restrict ourselves on the investigation of a multicarrier CDMA transmission. The frequency correlation between the fading amplitudes of the carriers is given by the delay powe...

This paper presents a investigation on the performance of security under κ-μ shadowed fading channels using the Wyner’s classic wiretap model. A better fit was presented for the κ-μ shadowed fading channel curves in relation to other fading models, as Rayleigh and Nakagami-m. Results and analyses are obtained through the Secrecy Outage Probability, the Strictly Positive Secrecy Capacity and Ave...

The Weibull-gamma (WG) distribution, which is appropriate for modelling fading environments when multipath is superimposed on shadowing, is introduced and studied. For this composite distribution the probability density, cumulative distribution, characteristic functions and the moments are derived in closed form. Furthermore, the average bit error and outage probabilities of a receiver operatin...

In this paper, we derive a capacity region for Gaussian fading multiple access degraded relay channel with partial channel state information (CSI) at the transmitters (CSIT) and perfect CSI at the receiver (CSIR). The achievable rate region obtained by Kramer-Wijngaarden is a special case of our region. Keywords-Gaussian fading channel; channel state information (CSI); discrete multiple access ...

In this paper, the physical layer security aspects of a wireless framework over ????? shadowed (AKMS) fading channel are examined by acquiring closed-form novel expressions average secrecy capacity, secure outage probability (SOP), and strictly positive capacity. The lower bound SOP is derived along with asymptotic expression at high signal-to-noise ratio regime in order to achieve diversity ga...

This work is devoted to the formulation and derivation of the η−μ/gamma and λ−μ/gamma distributions which correspond to physical fading models. These distributions are composite and are based on the η − μ and λ− μ generalized multipath models, respectively, and the gamma shadowing model. Novel analytic expressions are derived for the corresponding envelope probability density functions. Importa...
