Closed-Form Expressions for Secrecy Capacity over Correlated Rayleigh Fading Channels
نویسندگان
چکیده
We investigate the secure communications over correlated wiretap Rayleigh fading channels assuming the full channel state information (CSI) available. Based on the information theoretic formulation, we derive closed-form expressions for the average secrecy capacity and the outage probability. Simulation results confirm our analytical expressions.

Energy Detection of Unknown Signals over Composite multipath/shadowing Fading Channels
In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...

In this paper, we derive closed form expression for outage probability and infinite series expressions for exact and approximate symbol error rate (SER) and capacity of multiple input multiple output systems with transmit antenna selection (TAS) over generalized independent and identically distributed k ¡ m fading channels. The results are applicable to systems employing maximal ratio combining...
متن کاملCapacity and Error Probability Analysis for Orthogonal Space-Time Block Codes over Correlated Rayleigh and Rician Fading Channels
In this paper, the capacity and error probability of orthogonal space-time block codes (STBCs) are presented for PAM/PSK/QAM modulation in correlated flat fading channels. We consider an equivalent scalar AWGN (additive white Gaussian noise) channel with a channel gain proportional to the Frobenius norm of the matrix channel. A unified approach to the error probability analysis for correlated R...
متن کاملApproximate distribution of capacity of Rayleigh fading MIMO channels
Approximate closed-form density and distribution functions for the capacity of multiple-input multiple-output (MIMO) radio systems in spatially semi-correlated Rayleigh fading channels are derived. The approximations are given in terms of the Meijer G-function, hence allowing easy numerical evaluation of capacity outage probabilities with, for example, Maple or Mathematica. Introduction: We con...
متن کاملAn Analysis Modeling Architecture for Supporting Physical Layer Security of Wireless Networks under Hardware Impairments
In this paper, we study physical layer security (PLS) of wireless networks in presence of one eavesdropper. Assume that the channel state information (CSI) of the eavesdropper cannot be obtained at the transmitter, such as CSI can be then estimated through the CSI of a torch node. In addition, a practical issue of wireless nodes, i.e., hardware impairment (HI), is considered at the source node ...
