Center node: "cooperative diversity with mobile nodes outage capacity rates and durations"
  Abstract: A complete evaluation of the benefits of cooperative diversi ty schemes does not only include the outage and error rate performance but also the second-order statistics of the achievable informationtheoretic capacity. In a non-ergodic fading channel, the sy stem is in outage when the destination cannot decode the fixed-rate transmitted signal with negligible er ror probability. Because of the Doppler effect, which is induced by the mobility of the wireless nodes, these outage capacity events are correlated. In this paper, we derive exact expressions for the average outage rate (AOR) and the average outage duration (AOD) of three well-known cooperative diversity protocols operating in slow Rayleigh fading channels: variable-gain amplify-and-forward, decode-and-forward, and selection decode-and-forward relaying. Furthermore, we derive asymptotically tight high signal-to-noise ratio (SNR) approximations for the AORs and the AODs, which offer important insights into the influence of various system and channel parameters. In the high SNR region, we show that the AORs exhibit a similar behavior as the outage probabilities of the three considered cooperative d iversity protocols.
