Adaptive resolution-constrained scalar multiple-description coding
We consider adaptive two-channel multiple-description coding. We provide an analytical method for designing a resolutionconstrained symmetrical multiple-description coder that use...

A realistic performance analysis for practical channel-aware scheduling
It is well-known that opportunistic transmission schemes are sumcapacity optimal, in the Shannon sense, for symmetric cellular networks with single-antenna transceivers. However, ...

Multiuser MIMO Downlink with Limited Feedback Using Transmit-Beam Matching
— The multiuser multiple-input multiple-output (MIMO) broadcast channel uses multiple antennas at the transmitter to simultaneously deliver information to multiple users. Despite...

On the Stability and Delay of Channel-Aware Slotted ALOHA with Imperfect CSI
—In this work, we study the effect of imperfect channel-state information (CSI) on the stability and delay of a two-user channel-aware slotted ALOHA system. We assume that the ch...

Rate-efficient visual correspondences using random projections
We consider the problem of establishing visual correspondences in a distributed and rate-efficient fashion by broadcasting compact descriptors. Establishing visual correspondence...
