Outage probability in multiple antenna systems
European Transactions on Telecommunications, 2007AbstractMultiple transmit antennas improve the ergodic and outage capacity of wireless systems. Spatial properties of the channel including the transmit antenna array affect the optimum transmission strategy as well as the achievable capacity and average throughput.

Outage probabilities of wireless systems with beamforming
14th Annual International Conference on Wireless and Optical Communications, 2005. WOCC 2005, 2005Summary form only given. Recent years, beamforming techniques have received great interests and it can achieve performance and capacity enhancement without the need for additional power or spectrum. They can be implemented through conventional beamforming, minimum variance distortionless response (MVDR) beamforming, and linear constrained minimum ...

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.

Spatial Outage Probability Formula for CDMA Networks
2007 IEEE 66th Vehicular Technology Conference, 2007In this paper, we propose a new framework for the study of cellular networks called the fluid model and we derive from this model analytical formulas for interference, outage probability, and spatial outage probability. The key idea of the fluid model is to consider the discrete base stations (BS) entities as a continuum of transmitters which are ...

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).

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.

Minimizing outage probability for a class of MIMO channels
2009 11th Canadian Workshop on Information Theory, 2009In this paper we investigate the outage probability of Multiple-Input Multiple-Output (MIMO) channels, when the probability distribution of the channel gains is not completely known to the transmitter and receiver. The partial knowledge of a true probability distribution of the channel ν H (h) is modelled by a relative entropy constraint H(ν H ||µ H ...

Outage capacity and probability for a class of MIMO channels
2010 4th International Symposium on Communications, Control and Signal Processing (ISCCSP), 2010This paper is concerned with outage capacity and probability of Multiple-Input Multiple-Output (MIMO) systems for a class of channel distributions. The results illustrate how outage probability and capacity degrade as a function of the uncertainty class. Examples are given to support the conclusions.
