Optimal Signaling for Single Transmit Antenna Selection with Erroneous Feedback
We consider a MIMO system where error-prone feedback from the receiver is used by the transmitter to select a single optimum antenna to transmit data. Such error-prone feedback is...

Optimal CWmin selection for achieving proportional fairness in multi-rate 802.11e WLANs: test-bed implementation and evaluation
We investigate the optimal selection of minimum contention window values to achieve proportional fairness in a multirate IEEE 802.11e test-bed. Unlike other approaches, the propos...

On the Optimal Ordering of Maps and Selections under Factorization
The query optimizer of a database system is confronted with two aspects when handling user-defined functions (UDFs) in query predicates: the vast differences in evaluation costs b...

Optimizing network-coded cooperative communications via joint session grouping and relay node selection
Abstract—Network-coded cooperative communications (NCCC) is a new paradigm in wireless networks that employs network coding (NC) to improve the performance of CC. The core mechan...
