Serial relaying communications over generalized-gamma fading channels
In this paper, a study on the end-to-end performance of multi-hop non-regenerative relaying networks over independent generalized-gamma (GG) fading channels is presented. Using an upper bound for the end-to-end signal-to-noise ratio (SNR), novel closed-form expressions for the probability density function, the moments, and the moments-generating function of the end-to-end SNR are presented. Bas...
متن کاملApproximate SER of Cooperative Communication Over Generalized k−μ and η−μ Fading Channels
In this paper, closed form expressions for approximate symbol error rate (SER) are obtained using moment generating function (MGF) for a two branch cooperative communication system over generalized κ−μ and η−μ i.i.d. fading channels for BPSK and QAM modulation schemes. Selective Decode and Forward protocol is used at the relay transmitter. At the destination Maximal Ratio Combining (MRC) is use...
متن کاملPhysical Layer Secrecy Performance Analysis over Rayleigh/Nakagami Fading Channels
1 Abstract—The broadcast nature of wireless communications makes it vulnerable to attack or eavesdropping. Therefore, information security is an important issue in wireless communications, especially in distributed networks such as wireless sensor networks and ad hoc wireless networks. In this paper, we present the physical layer secrecy performance analysis of singleinput single-output (SISO) ...
متن کاملCognitive Cooperative Networks in Dual-Hop Relaying Asymmetric Fading Channels
In cognitive relay networks (CRNs), all of previous works have considered symmetric fading channels. However, in practical wireless propagation scenarios, it is likely that the different channels associated with secondary user (SU) and primary user (PU) may undergo different fading characteristics. Therefore, in this paper, we assume that the channels of the secondary network (SU-source→SU-rela...
متن کاملAdaptive selective relaying in cooperative free-space optical systems over atmospheric turbulence and misalignment fading channels.
In this paper, a novel adaptive cooperative protocol with multiple relays using detect-and-forward (DF) over atmospheric turbulence channels with pointing errors is proposed. The adaptive DF cooperative protocol here analyzed is based on the selection of the optical path, source-destination or different source-relay links, with a greater value of fading gain or irradiance, maintaining a high di...
