Conditional outage performance analysis framework for OFDM channels
2013 IEEE International Conference on Communications (ICC), 2013 The channel state information at the transmitter side (CSIT) is playing a more and more important role in the design of OFDM/OFDMA communication systems. Unfortunately, it is not trivial to conduct a performance analysis of OFDM systems with partial CSIT.

Outage Performance for Compute-and-Forward in Generalized Multi-Way Relay Channels
IEEE Communications Letters, 2012 The compute-and-forward (CPF) relaying strategy proposed by Nazer and Gastpar has been proven to achieve a significant improvement in "computation rate" than conventional relaying strategies in the multiple-access channel (MAC).

Outage Performance Analysis of Vertical Underwater VLC Links
2022 30th Signal Processing and Communications Applications Conference (SIU), 2022In this paper, we investigate the outage performance of vertical stratified underwater optical links in the presence of moderate/strong turbulence conditions. Specifically, we consider the cascaded Gamma-Gamma turbulence channel model and derive a closed-form expression for outage probability.

Outage Performance of Satellite-Aerial-Terrestrial Network
2019 IEEE Globecom Workshops (GC Wkshps), 2019In this paper, we investigate the performance of an amplify-and-forward satellite-aerial-terrestrial network (SATN) with a multi-antenna unmanned aerial vehicle (UAV) relay, where the satellite-UAV link undergoes correlated Shadowed-Rician fading while the UAV-terrestrial links experience correlated Rician fading, respectively.

Outage Performance in Cooperative IoT Networks with Energy Harvesting
2020 International Wireless Communications and Mobile Computing (IWCMC), 2020In this paper, we consider a wireless-powered cooperative communication network (WPCCN) consisting of one access point (A), one Power Beacon (B), one source and one relay. In contrast to conventional cooperative networks, the source and relay in the considered network have no embedded energy supply.

Outage performance of mobile V2V cooperative networks
Physical Communication, 2019Abstract In this paper, the outage probability (OP) performance of mobile vehicle-to-vehicle (V2V) networks with incremental hybrid decode–amplify–forward (IHDAF) relaying is investigated. Exact closed-form expressions for the OP are derived. The impact of the power allocation on the OP is evaluated. Theoretical and Monte-Carlo simulation results are

BlockOut: Blocking and Outage in a Single Performance Measure
IEEE Transactions on Vehicular Technology, 2014Blocking probability is widely used as a performance measure for dimensioning a variety of networks, including wireless communication systems. However, the performance of the system may be affected by factors other than traffic and resources, i.e., the primary ingredients in blocking. Such factors include interference, energy consumption, service delay

Outage Performance of Cooperative Systems Under IQ Imbalance
IEEE Transactions on Communications, 2014In this contribution, we investigate the outage performance of OFDM-based Decode and Forward (DF), Amplify and Forward (AF) and Controlled DF (CDF) cooperative systems under IQ Imbalance (IQI). In particular, tractable and compact approximate outage probability expressions are derived and the effect of the different IQI parameters is analyzed for ...
