Improving Outage Performance: Outage Optimization Process

Volume 1: Plant Operations, Maintenance and Life Cycle; Component Reliability and Materials Issues; Codes, Standards, Licensing and Regulatory Issues; Fuel Cycle and High Level Waste Management, 2006
Planned outage performance is a key measure of how well an Nuclear Power Plant (NPP) is operated. Performance during planned outages strongly affects virtually all of a plant’s performance metrics. In recognition of this fact, NPP operators worldwide have and continue to focus on improving their outage performance.

U.S. Network Reliability Issues and Major Outage Performance

Proceedings IEEE Symposium on Computers and Communications, 2002
In the past decade the United States telecommunications industry has been under much scrutiny as a result of a number of major network outages. These outages, which affected millions of customers, ranged from power and fire related problems to a software error affecting the common channel signaling network. The industry reacted promptly and positively.

On the Outage Performance of JT-CoMP-CNOMA Networks With SWIPT

IEEE Communications Letters, 2021
In this letter, we investigate the outage performance of a joint transmission coordinated multipoint cooperative non-orthogonal multiple access (JT-CoMP-CNOMA) network. It is assumed that there is no direct links between the base stations and the cell-edge user, and thus the cell-centre users act as relays for the cell-edge user.

Outage Performance Analysis of Cooperative Diversity

2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control, 2012
Cooperative diversity has attracted great attention in recent years. In such a system, even single-antenna terminals can achieve spatial diversity with the help of other terminals. In this paper, we focus on the outage performance of cooperative diversity. The outage probabilities of several mean cooperative protocols are analyzed and compared.

Outage Performance for IDF Relaying Mobile Cooperative Networks

Mobile Networks and Applications, 2017
Cooperative communication has emerged as a key technique in fifth generation (5G) mobile wireless networks. In this paper, with incremental decode-and-forward (IDF) relaying and transmit antenna selection (TAS), we investigate the outage probability (OP) performance of mobile cooperative networks.

Outage Performance of Cooperative Relay Using STBC Systems

Wireless Personal Communications, 2009
We analyze the outage performance of the cooperative relay with the decode- and-forward protocol under Rayleigh fading channels. The technique of orthogonal space---time block coding is applied at the links of source-relay, source-destination and relay-destination. A closed-form expression for the outage probability is derived.

Analytical outage performance of cognitive small cell network

2014 IEEE Online Conference on Green Communications (OnlineGreenComm), 2014
Spectral efficiency (SE) and energy efficiency (EE) are the critical challenges for the next generation cellular network (NGCN). Small cells deployment and cognitive radio which facilitates efficient utilization of radio spectrum are the promising techniques for evolution of the NGCN.

Outage Performance of Cooperative NOMA Networks with Hardware Impairments

2018 IEEE Global Communications Conference (GLOBECOM), 2018
We investigate the outage performance of cooperative non-orthogonal multiple access (NOMA) networks with transceiver hardware impairments, where the estimated channel state information and α-μ fading channels are considered. Closed-form expressions for the outage probability of cooperative NOMA networks are derived for two representative ...

Wireless Powered Cognitive Cooperative Networks: Outage Performance

2019 13th International Conference on Signal Processing and Communication Systems (ICSPCS), 2019
This paper jointly studies cognitive radio (CR) and non-orthogonal multiple access (NOMA) networks by adopting an energy restricted amplify-and-forward relay. We study the outage performance of NOMA secondary destination users (U 1 and U 2 ). Then, power allocation (PA) factors based on the NOMA users’ outage fairness are evaluated for different ...

Outage performance of multi-antenna multicasting for wireless networks

IEEE Transactions on Wireless Communications, 2009
Wireless cellular networks often need to convey the same data to multiple users simultaneously. This kind of transmission is known as physical layer multicasting. Unfortunately, when any user fails to receive the data correctly, the information must be retransmitted to all the users, resulting in a waste of radio resources.
