Outage Analysis of Decode-and-Forward Relaying Over Nakagami- Fading Channels

In this letter, closed-form outage probability expressions are presented for an -relays dual-hop plus a direct link network, in which the decode-and-forward relaying protocol is employed. Our analysis significantly extends previous results on Rayleigh fading, considering a Nakagamifading environment with either equal or distinct second hops fading parameters to average power ratios. Various num...

A Comparative Study of Relaying Schemes with Decode-and-Forward over Nakagami-m Fading Channels

Utilizing relaying techniques to improve performance of wireless systems is a promising avenue. However, it is crucial to understand what type of relaying schemes should be used for achieving different performance objectives under realistic fading conditions. In this paper, we present a general framework for modelling and evaluating the performance of relaying schemes based on the decode-and-fo...

Optimization of relay placement and power allocation for decode-and-forward cooperative relaying over correlated shadowed fading channels

In this paper, we investigate the relay placement and power allocation for decode-and-forward (DF) cooperative relaying over correlated lognormal shadowed Rayleigh fading channels. Assuming that maximum-ratio combining is performed at the destination, we first derive an upper bound of symbol error rate (SER) withM-phase-shift keying (PSK) modulation. Then, three optimization problems are formul...

An Upper Bound of Soft Decode and Forward Relaying Over Rayleigh Fading Channels

In this paper, we investigate a distributed turbo code (DTC) scheme dedicated to L-relay channels operating in the soft-decode-and-forward (soft-DF) mode. At the destination, the received replicas are combined using the maximal ratio combining (MRC). Then, we define the explicit upper bound for error rate assuming Binary phase shift keying (BPSK) transmission for fully interleaved channels with...

Fading Channels in the Power Limited Regime

The tradeoff of spectral efficiency vs energy-per information bi t (normalized to the noise level ,?&/No) is the key measure of the capaci ty of channels in the power-limited regime. This paper finds the fundamental bandwidth-power tradeoff of a general class of channels in the wideband regime in which the spectral efficiency is small but nonzero.
