In this paper, we investigate cooperative diversity using amplify-and-forward (AF) relaying over independent and identically distributed (i.i.d.) Weibull fading channels with selection combining (SC) and derive a approximate closed form expression for the probability density function (PDF) of the signal-to-noise ratio (SNR) for the Weibull fading distribution, Then closed form expression for the average...
This paper studies a destination-driven cooperative diversity protocol for multihop wireless networks. The regenerative outage performances of the proposed protocol are developed over independent but not identically distributed (i.n.d) Nakagami fading channels. The numerical results show that the proposed protocol not only provides an effective selection scheme for cooperative nodes but achieves a...
This paper proposes a multi-node cooperative threshold selection maximum ratio combining (TS-MRC) system for multi-hop wireless networks. We analyze and derive the regenerative outage probability of TS-MRC system and MRC-based cooperative system over Nakagami fading channels. The numerical and simulation results show that TS-MRC achieves a tradeoff between the system performance and the process capability...
This paper investigates two-phase cooperative diversity protocols for multi-hop wireless networks over generalized fading environments. We derive their regenerative outage probability expressions and achieve their diversity orders at high average signal-to-noise ratio (ASNR) in both the single-node relaying case and the multiple-node relaying case. The theoretical analysis and simulation results show...
This paper investigates two-phase cooperative diversity protocols for multihop wireless networks over generalized fading environments. We analyze their regenerative outage probability in term of symmetrical and asymmetrical network configurations. Their generalized diversity order expressions are derived at high average signal-to-noise ratio (ASNR). The theoretical and simulation results show that...
