are defined as the channel being attenuated for at least a time duration (minimum duration outage). Also, extensions of this concept and applications to higher-layer performance are discussed. I. INTRODUCTION The quality of wireless channels fluctuates randomly due to a number of unpredictable effects

constructed from pairs of distinct code sequences. The minimum rank among these matrices quantifies the diversity gain, while the minimum determinant of these matrices quantifies the coding gain. The results are then extended to fast fading channels. The design criteria are used to design trellis codes

Abstract—The multicast beamforming problem is considered from the viewpoint of minimizing outage probability subject to a transmit power constraint. The main difference with the point-to-point transmit beamforming problem is that in multicast beamforming the channel is naturally modeled as a

) and that plasma virions have a mean lifespan of 0.3 days (t 1=2 = 0:24 days). The average total HIV-1 production was 10:3 \Theta 10 9 virions per day, which is substantially higher than previous minimum estimates. Our results also suggest that the minimum duration of the HIV-1 life cycle in vivo is 1.2 days

We consider the problem of establishing minimum-cost multicast connections over coded packet networks, i.e., packet networks where the contents of outgoing packets are arbitrary, causal functions of the contents of received packets. We consider both wireline and wireless packet networks as well

Abstract — This paper focuses on how the system behavior of highly reliable telecommunications systems can be characterized with respect to the distribution of outage durations and the escalating recovery mechanisms implemented in the system. We develop models that can be used to predict the outage

failure, and (iii) scan withdrawal under the interference-limited condition in a multicell system. We derive their expressions and provide a generalized framework for the analysis of handover measurement failure and target cell quality by the best signal quality and minimum duration outage.

Abstract — In this paper, assuming transmission with fixed rate and fixed power, we derive the average duration of capacity outage and non-outage events of selective decode-and-forward relaying with repetition coding over slow Rayleigh fading channels. Furthermore, we develop high signal

Abstract—We consider the problem of cooperative broadcasting for minimum outage in wireless networks. We consider wireless multihop broadcast as a set of transmitters that transmit in a certain order. The receiving nodes are able to combine all the previous transmissions and achieve better received
