Performance Analysis of Dual-Hop Systems with Decode-and-Forward Relays over Generalized Fading Channels
Dual-hop transmission systems employing decodeand-forward relay are studied in this paper. The examination has been done for independent, but not necessarily identical Extended Generalized-K fading channels. New, exact, closedform expressions are derived for the outage probability, the nth moments of the end-to-end signal-to-noise ratio (SNR), and the ergodic capacity. Moreover, the average sym...
متن کاملOutage Performance of Line of Sight Decode and Forward Relays in Cooperative VANETs
Cooperative communications boasts attractive performance enhancements in vehicular communication environment. Amplify and Forward (AF) and Decode and Forward (DF) relaying have been proposed and analysed for vehicular networks in recent literature. For the study of performance enhancements in this area vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) channel model is crucial. Vehicu...
متن کاملOutage Performance of Decode-and-Forward in Two-Way Relaying with Outdated Channel State Information
In this paper, we analyze the outage behavior of decode-and-forward relaying in the context of selective two-way cooperative systems. First, a new relay selection metric is proposed to take into consideration both transmission rates and instantaneous link conditions between cooperating nodes. Afterwards, the outage probability of the proposed system is derived for Nakagami-m fading channels in ...
متن کاملCapacity Performance Analysis for Decode-and-Forward OFDM Dual-Hop System
In this paper, we propose an exact analytical technique to evaluate the average capacity of a dual-hop OFDM relay system with decode-and-forward protocol in an independent and identical distribution (i.i.d.) Rayleigh fading channel. Four schemes, (no) matching “and” or “or” (no) power allocation, will be considered. First, the probability density function (pdf) for the end-to-end power channel ...
متن کاملChirawat Kotchasarn: Performance Analysis of Multi-hop Decode and Forward
In this paper, we present the performance analysis of multi-hop decode-and-forward (DF) cooperative communications under Rayleigh fading channel. The source, multiple relays and destination nodes are equipped with single antenna transceiver while the transmission channels are assumed to be mutually independent. A time-division channel allocation scheme is occupied in order to realize orthogonal...
