Outage probability for decode-and-forward cooperative diversity with selective combining in cellular networks.
ABSTRACT This paper analyzes the outage probability for a decode-and-forward (DF) cooperative diversity system with selective combining, for the case of a log-normal Nakagami faded desired signal and log-normal Rayleigh faded co-channel interferers. The outage probability is compared to that of a dual-receive antenna system also with selective combining. The results of the analysis show that the proposed DF cooperative diversity system can result in a lower outage probability than the corresponding dual-receive antenna system, but only when the relay is located in a particular region of the cell with respect to the mobile station location.

Conference Paper: Outage-Optimal Cooperative Communications with Regenerative Relays[Show abstract] [Hide abstract]
ABSTRACT: In this paper, we put forth simple opportunistic relaying with decode-and-forward (DaF) or regenerative processing strategy, under an aggregate power constraint. In particular, we consider distributed relay-selection algorithms requiring only local channel knowledge. We prove that opportunistic single relay selection with DaF strategy is outage-optimal, that is, it is equivalent in outage behavior to the optimal DaF strategy that employs all potential relays.Information Sciences and Systems, 2006 40th Annual Conference on; 04/2006

ABSTRACT: In this paper, the performances analysis of cooperative-diversity networks using adaptive decode-and-forward (DF) relaying over independent non-identical flat Nakagami-m fading channels is investigated. We derive closed-form expressions for the error probability, outage probability and average channel capacity, and analyze their dependence on the channel parameters. In adaptive DF relaying, among M relays that can participate, only C relays (C les M), with good channels to the source, decode and forward (retransmit) the source information to the destination. Then, the destination combines the direct and the indirect signals using maximum ratio combining (MRC) technique. We derive a closed-form expression for the the moment generating function (MGF) of the total signal-to-noise ratio (SNR) at the destination node. Then, we find a closed-form expression for the probability density function (PDF) of the total SNR at the destination. This PDF is used to derive the closed-form expressions of the performance metrics. Computer simulations are used to validate our analytical results. Results show the significant performance improvement due to the use of the adaptive DF cooperative diversity. Also, results indicate that increasing the number of relays will not always decrease the outage probability.Proceedings of IEEE International Conference on Communications, ICC 2009, Dresden, Germany, 14-18 June 2009; 01/2009
Conference Paper: Increasing uplink capacity via user cooperation diversity[Show abstract] [Hide abstract]
ABSTRACT: Mobile users' capacity is limited by the fact that within the duration of any given call, they experience severe variations in signal attenuation, thereby necessitating the use of some type of diversity. We are proposing a new form of diversity, whereby diversity gains are achieved via the cooperation of in-cell users. Results show that, even though the inter-user channel is noisy, cooperation leads not only to an increase in capacity but also to a more robust system, where users' achievable rates are less susceptible to channel variationsInformation Theory, 1998.
