Cooperation with an untrusted relay: a secrecy perspective
We consider the communication scenario where a source-destination pair wishes to keep the information secret from a relay node despite wanting to enlist its help. For this scenario...

A Queued-Code Based on LDPC Block Codes
— A ‘queued-code’ is a novel code which allows for instantaneous rate adaptation, to match the current channel state information (CSI), assumed known to the transmitter. Prev...
