Outage Analysis of Cooperative OFDM Systems with Nonlinear Amplifiers and Relay Selection
Resumo—Comunicações cooperativas surgiram como uma promissora solução para redes sem fio. Em particular, recentemente tem-se presenciado um interesse crescente em sistemas cooperativos do tipo amplifica-e-encaminha com seleção de relay. Por outro lado, a técnica de multiplexação por divisão em frequências ortogonais (OFDM) tem se mostrado ser uma tecnologia chave para os futuros sistemas de com...
متن کاملOutage Probability Analysis of Multiple-access Relay Channel with Network Coding and Relay Selection ⋆
The Multiple-access Relay Channel (MARC) has been considered as a promising technique in next generation wireless communication networks. In this work, we study a Network Coding based Multiaccess Relay Channel (NC-MARC) where a decode-and-forward relaying and a static XOR network coding are considered for the one-way relaying system. The system consists of two transmitters communicating with a ...
متن کاملAsymptotic Outage Probability Analysis for General Fixed-Gain Amplify-and-Forward Multihop Relay Systems
In this paper, we present an analysis of the outage probability for fixed-gain amplify-and-forward (AF) multihop relay links operating in the high SNR regime. Our analysis exploits properties of Mellin transforms to derive an asymptotic approximation that is accurate even when the per-hop channel gains adhere to completely different fading models. The main result contained in the paper is a gen...
متن کاملOutage Performance Analysis in Cognitive Wireless Relay Networks
Abstract: The analysis the outage performance of suggested Cognitive Wireless Relay Network (CWRN) which consists of a source, a destination and M cognitive relay nodes and M primary user nodes. In this study, we mainly study that the cognitive relay nodes impact on the outage performance of proposed CWRN over Rayleigh channels under both the peak and average interference power constraints. Fir...
متن کاملOutage Performance of Cognitive Wireless Relay Networks
In this paper, we investigate the outage performance of cognitive wireless relay networks where source nodes communicate to their destinations via multiple hops facilitated by intermediate cognitive nodes able to acquire spectrum holes. Specifically, we consider a model that consists of a source node, a destination node, and a group of network clusters each consisting of a number of cognitive (...
