Multiuser broadcast erasure channel with feedback - capacity and algorithms
We consider the N-user broadcast erasure channel where feedback from the users is fed back to the transmitter in the form of ACK messages. We provide a generic outer bound to the ...

How to beat the sphere-packing bound with feedback
The sphere-packing bound Esp(R) bounds the reliability function for fixed-length block-codes. For symmetric channels, it remains a valid bound even when strictly causal noiseless ...

On the Capacity of Multiple Access Channels with State Information and Feedback
In this correspondence, the multiple access channel (MAC) with channel state is analyzed in a scenario where a) the channel state is known non-causally to the transmitters and b) t...

On the use of relevance feedback in IR-based concept location
Concept location is a critical activity during software evolution as it produces the location where a change is to start in response to a modification request, such as, a bug repo...

Minimum BER Transmit Beamforming for MIMO-OFDM Systems with Finite Rate Feedback
— In this paper, we consider minimum bit error rate (BER) beamforming (BF) for multiple–input multiple–output orthogonal frequency division multiplexing (MIMO–OFDM) systems...
