Outage Probabilities of Wireless Systems with LCMV Beamforming
IEEE Transactions on Wireless Communications, 2007This paper investigates the outage probability of a wireless system with linear constrained minimum variance (LCMV) beamforming using a uniform linear array beamformer. LCMV beamforming is able to perfectly cancel a number of dominant interferers while other interferers remain.

On the asymptotic behavior of the outage probability forMIMO systems
IEEE Wireless Communications and Networking Conference, 2005, 2005The asymptotic behavior of the outage probability has been studied recently with the assumption that the receiver is equipped with a single antenna. In this paper, we extend this study to an arbitrary number of receive antennas. We use the Gaussian approximation for the distribution of the random mutual information to derive a threshold for the outage ...

Outage probability in a circle with uniformly distributed users
2012 25th IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2012Outage probability is one of the most important metrics that can be used to study the performance of wireless networks. In this paper, we evaluate outage probability of users which are uniformly distributed in a circular cell. The outage probability is determined in terms of generic parameters and is compared with well-known formula of the percentage ...

Outage Probability Study in a NOMA Relay System
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017In this paper two different non-orthogonal multiple access (NOMA) relay schemes are analyzed, namely NOMA cooperative scheme and NOMA TDMA scheme. Both schemes apply NOMA in the first stage by sending NOMA superimposed signals to relays. Relays then forward the messages to two UEs in the second stage. In the second stage of NOMA cooperative scheme, two

A General Numerical Method for Computing the Probability of Outage
2009 IEEE Wireless Communications and Networking Conference, 2009The outage probability is a fundamental performance metric, which has been widely investigated in the literature. In this paper, we develop a general method to compute the outage given the moment generating function (MGF). When computing the outage using the MGF, integration along the standard Bromwich contour suffers from a loss of accuracy due to ...

Approximating the Outage Probability of Parallel Fading Channels
IEEE Communications Letters, 2015We develop an approximation for the outage probability of a parallel channel where the subchannel statistics satisfy mild conditions. The main result is in the form of a functional of the density function that describes the statistics of the subchannel powers.

QoS-based outage probability for diversity reception
2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003In a digital mobile radio system with fast fading superimposed on slow fading, the symbol error probability (SEP) alone is not sufficient to describe the link quality. In this case, a reasonable performance measure related to the slow channel variations is the outage probability (OP).

Outage probability analysis of heterogeneous relay networks
2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018The heterogeneous wireless network is considered to be a cornerstone of the system architectural design of the next cellular network generations such as the fifth generation (5G) to alleviate the imminent capacity crunch. With the heterogeneity of the 5G cellular network, it is inevitable to have different statistical channel models within the same ...

The impact of different services on the outage probability in UMTS
IEEE 54th Vehicular Technology Conference. VTC Fall 2001. Proceedings (Cat. No.01CH37211), 2002In this paper, we deal with the uplink outage probability for a UMTS cellular network at a reference base station equipped with a smart antenna. Users are assumed to be distributed according to a planar Poisson point process. Their respective transmission rates are modeled by independent random variables.

Outage probability analysis for device-to-device system
2016 IEEE International Conference on Communications (ICC), 2016Device-to-Device (D2D) communication capability within a cellular network is an integral part of the LTE-Advanced standards since 3GPP release 12. D2D communication is being targeted for traffic loading applications and proximity based services, and has the potential to enhance spectrum efficiency, overall system throughput and energy efficiency ...
