Average performance analysis of a link adaptation based on the maximization of the minimum user rate
نویسندگان
چکیده
In the context of adaptive DS-CDMA transmissions, we study average performance of a link adaptation based on the maximization of the minimum information rate subject to a target bit error rate for erroneous frames. Analytical expressions and bounds are derived when Rayleigh fading environment is assumed. Results are also compared to a link adaptation strategy based on the total throughput maximization.

Sum-Rate Maximization Based on Power Constraints for Cooperative AF Relay Networks
In this paper, our objective is maximizing total sum-rate subject to power constraints on total relay transmit power or individual relay powers, for amplify-and-forward single-antenna relay-based wireless communication networks. We derive a closed-form solution for the total power constraint optimization problem and show that the individual relay power constraints optimization problem is a quad...

متن کاملLink Adaptation for Framed Multimedia Data Transmission over a DS-CDMA Communication System
In the context of frame-based multimedia wireless transmission, a link adaptation strategy is proposed, assuming that the source decoder may accept some remaining errors at the output of the channel decoder. Based on a target mean bit error rate for erroneous frames, a minimum bit-energy-to-equivalent-noise ratio is chosen. Under this constraint, a new link adaptation criterion is proposed: the...
