A simple Encoding Scheme to Achieve the Capacity of Half-Duplex Relay Channel
Advances in Electrical and Electronic Engineering, 2022 In this paper, the Half-Duplex Relay Channel (HDRC) is thoroughly investigated. Even though this channel model is widely studied, the capacity is not yet fully understood and particularly has not been tightly expressed.

On the Multiple Access Channel With Asynchronous Cognition [PDF]
IEEE Transactions on Information Theory, 2016 In this paper we introduce the two-user asynchronous cognitive multiple access channel (ACMAC). This channel model includes two transmitters, an uninformed one, and an informed one which knows prior to the beginning of a transmission the message which the uninformed transmitter is about to send.
