Spatial Outage Probability for Cellular Networks
IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007 In this paper, we propose a new framework for the study of cellular networks called the fluid model and we derive from this model analytical formulas for interference, outage probability, and spatial outage probability. The key idea of the fluid model is to consider the discrete base stations (BS) entities as a continuum of transmitters which are ...

Outage probability of multihop relay networks
2013 9th International Wireless Communications and Mobile Computing Conference (IWCMC), 2013 In 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.

IEEE Transactions on Wireless Communications, 2012 In this paper, the outage probability and outage-based beam design for multiple-input multiple-output (MIMO) interference channels are considered. First, closed-form expressions for the outage probability in MIMO interference channels are derived under ...

Elementary expressions for outage probability
IEEE Communications Letters, 2006Elementary expressions are derived for the outage probabilities of maximal ratio combining in the presence co-channel interference considered by Zhang and Beaulieu. The branch gains of the desired user signal and interfering signals experience Rayleigh fading and have the same correlation matrix.

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 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 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.

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
