Precoding for Outage Probability Minimization on Block Fading Channels [PDF]
, 2012 The outage probability limit is a fundamental and achievable lower bound on the word error rate of coded communication systems affected by fading. This limit is mainly determined by two parameters: the diversity order and the coding gain.

Outage Probability in Arbitrarily-Shaped Finite Wireless Networks [PDF]
, 2013 This paper analyzes the outage performance in finite wireless networks. Unlike most prior works, which either assumed a specific network shape or considered a special location of the reference receiver, we propose two general frameworks for analytically ...

International Journal of Distributed Sensor Networks, 2016 The high outage probability of an underwater wireless sensor may lead to high energy consumption. How to reduce the outage probability should be considered for underwater acoustic sensor networks (UASNs), where battery change is very difficult.

Outage Probability for MIMO MAC Channels [PDF]
Proceedings of the 1st International Conference on 5G for Ubiquitous Connectivity, 2014 In this paper, we investigate the outage probability for the mutual information of the sum rate for the MIMO (multiple input multiple output) MAC (multiple access channel) channel. We derive exact results for the “two users” case with two antennas and a general result for K users with an arbitrary number of antennas and different signal-to-noise ratios.
