On Outage Performance of Terahertz Wireless Communication Systems
IEEE Transactions on Communications, 2022 To expedite research progress on terahertz (THz) communications, we analyze the outage performance of THz communication systems by a compound channel model in this paper. Different from existing models, the compound channel model incorporates the effects of spreading loss, molecular absorption loss, shadowing, and multi-path fading via a composite ...

Outage Exponent: A Unified Performance Metric for Parallel Fading Channels
IEEE Transactions on Information Theory, 2013 The parallel fading channel, which consists of finite number of subchannels, is very important, because it can be used to formulate many practical communication systems.

Outage Performance of the Primary Service in Spectrum Sharing Networks [PDF]
IEEE Transactions on Mobile Computing, 2013 In this paper, we utilize stochastic geometry to analyze the primary service (PS) outage performance for spectrum sharing in Rayleigh fading environment. Using this approach, the impacts of the secondary service (SS) parameters and wireless environment on the PS outage probability are analyzed.

On the Outage Performance of Ambient Backscatter Communications [PDF]
IEEE Internet of Things Journal, 2020 Ambient backscatter communications (AmBackComs) have been recognized as a spectrum- and energy-efficient technology for Internet of Things, as it allows passive backscatter devices (BDs) to modulate their information into the legacy signals, e.g., cellular signals, and reflect them to their associated receivers while harvesting energy from the legacy ...

Outage Performance of Cross-Packet HARQ
IEEE Wireless Communications Letters, 2022 As opposed to hybrid automatic repeat request with incremental redundancy (HARQ-IR) that all the resources are occupied to resend the redundant information, cross-packet HARQ (XP-HARQ) allows the introduction of new information into retransmissions to substantially exploit the remaining resources.

Rate Splitting in the Presence of Untrusted Users: Outage and Secrecy Outage Performances
IEEE Open Journal of the Communications Society, 2022 In this contribution, a thorough investigation of the performance of rate splitting is conducted in terms of outage and secrecy outage for the simultaneous service to a near user and far user, where the latter attempts to overhear the message of the former. The source transmits a linear combination of the users’ common stream and private streams.

Outage Performance in Secure Cooperative NOMA [PDF]
2019 Iran Workshop on Communication and Information Theory (IWCIT), 2019 Enabling cooperation in a NOMA system is a promising approach to improve its performance. In this paper, we study the cooperation in a secure NOMA system, where the legitimate users are distributed uniformly in the network and the eavesdroppers are distributed according to a homogeneous Poisson point process.

Downlink outage performance of heterogeneous cellular networks [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 This paper derives tight performance upper and lower bounds on the downlink outage efficiency of K-tier heterogeneous cellular networks (HCNs) for general signal propagation models with Poisson distributed base stations in each tier. In particular, the proposed approach to analyze the outage metrics in a K-tier HCN allows for the use of general bounded
