Outage probability approximations for cooperative communication systems

2011 IEEE 13th International Conference on Communication Technology, 2011
Cooperative communication system has emerged as a significant concept which improves reliability and throughput in wireless communication systems. Some existing cooperative diversity protocols have been shown to increase the diversity order, allowing single-antenna nodes to cooperate with each other and achieve high performance like a real MIMO system.

Minimizing outage probability for arbitrary channel distributions

IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005
MIMO wireless systems have been a focus of research for several years, mainly because of the promise of increased channel capacity, extended range, and increased reliability. An aspect of this ongoing research has been concerned with transmit precoding given partial information of the channel.

Outage Probability Reduction through Inter-WBAN Cooperation

2019 2nd International Conference on Engineering Technology and its Applications (IICETA), 2019
The wireless body area networks (WBAN) cooperation is investigated and Inter-WBANs cooperation (IWC) protocol is designed in this paper. In such system, a sensor of the WBAN-1 transmits information to its coordinator node (CN1) and the coordinator node (CN2) of the neighbor WBAN 2, at same time, a sensor of the WBAN 2 transmits information to its ...

Outage probability constrained robust downlink collaborative beamforming

2011 International Conference on Wireless Communications and Signal Processing (WCSP), 2011
We consider a downlink collaborative relay network where communication between the base station and the terminal node is assisted by a cluster of relay nodes with imperfect channel state information (CSI). The equivalent condition for the probability constraint on the signal-to-noise-ratio (SNR) is derived, by modeling the CSI uncertainties as Gaussian.

QoS-based outage probability for diversity reception

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003
In 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).
