Outage probability for multimodal cooperative networks
2011 45th Annual Conference on Information Sciences and Systems, 2011We consider the performance of small-scale heterogeneous cooperative networks in which some nodes can transmit and/or receive using channels not available to other nodes, i.e., multimodal communication networks. As an example, we assume the presence of an additional wired channel in a conventional diamond relay network operating under the Laneman ...

Outage Probability for MIMO Relay Channel
IEEE Transactions on Communications, 2014The channel capacity for the multiple-input multiple-output (MIMO) relay channel is still an open problem. In view of this gap, upper and lower bounds were found by Wang et al., 2005. This paper presents an extensive study of mutual information and outage probability of Rayleigh fading MIMO relay channels based on the eigenvalues distribution for the ...

Outage probability of multihop relay networks
2013 9th International Wireless Communications and Mobile Computing Conference (IWCMC), 2013In this paper we analyze the outage performance of a multihop cooperative relay network where relays in the system can change positions dynamically and use all possible links to forward the message to the next hop over Rayleigh fading channels. We derive the general closed form expression of outage probability and asymptotic coding gain of the network.

Outage Probability of LDPC-Coded Systems
IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007Outage probability is an important performance measure of wireless communication systems operating in a fading environment. In this paper, we study the outage probability of low-density parity-check (LDPC) coded systems for slow fading channels (nonergodic channels) under the assumption that the transmitter knows only the channel statistics while the ...

On the Outage Probability of Distributed MAC With ZF Detection
IEEE Transactions on Communications, 2018Distributed scheduling is an attractive approach for the Multiple-Access Channel (MAC). However, when a subset of the users access the channel simultaneously, distributed rate coordination is necessary, and is a major challenge, since the channel capacity of each user highly depends on the channels of other active users.

On Outage Probability of Selection Cooperation
Wireless Personal Communications, 2012An exact and elementary expression is derived for the outage probability of selection cooperation. Its performance is compared versus known approximations. Some better approximations are proposed.

Analysis of Outage Probability for Cooperative Networks with HARQ
2007 IEEE International Symposium on Information Theory, 2007We derive the expressions of the outage probability for a wireless network that integrates hybrid automatic repeat request (HARQ) and coded cooperation among nodes. The medium access control (MAC) provides a HARQ protocol where the source node, upon a decoding failure at the destination node, transmits additional coded bits for the same data packet. If

Expressions for outage probability
European Transactions on Telecommunications, 2008AbstractThe outage probability for most wireless communications networks can be approximated by$R = {\rm Pr}(X_2 < X_1)$whereX1andX2are independent random variables. Here, a comprehensive collection of formulae is derived forRby assuming the most commonly known models forX1andX2.

PMD Outage Probabilities Revisited
OFC/NFOEC 2007 - 2007 Conference on Optical Fiber Communication and the National Fiber Optic Engineers Conference, 2007In the time intervals of its validity, the new hinge model for optical fiber transmission links requires a re-examination of the traditional concepts of PMD outage and their impact on system design.

Probable outages of shielded transmission lines
Electrical Engineering, 1937Based on the observed phenomenon that flashover of transmission-line towers provided with 2 overhead ground wires occurs only when the product of tower footing resistance and tower surge current exceeds the insulation strength, the probable outages that will occur on a line can be obtained by a simple method.
