On two-pair two-way relay channel with an intermittently available relay [PDF]

open access: green, 2015
When multiple users share the same resource for physical layer cooperation such as relay terminals in their vicinities, this shared resource may not be always available for every user, and it is critical for transmitting terminals to know whether other ...

Relay Selection with Network Coding in Two-Way Relay Channels [PDF]

open access: yes, 2010
In this paper, we consider the design of joint network coding (NC)and relay selection (RS) in two-way relay channels. In the proposed schemes, two users first sequentially broadcast their respective information to all the relays.

On the Non-Coherent Wideband Multipath Fading Relay Channel [PDF]

open access: yes, 2010
We investigate the multipath fading relay channel in the limit of a large bandwidth, and in the non-coherent setting, where the channel state is unknown to all terminals, including the relay and the destination.

Network-Coding-based Jamming With Triple Transmission Time Slots: A Method To Secure Transmission In An Extreme Case of Source-Wiretapping and Unshared Jamming Signal [PDF]

open access: yesEAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2021
This article resolves an extreme case in physical layer security: an eavesdropper, located near to a source, can spy on the jamming-seed if it is just cryptographically shared. The direct link between the source and destination is even unavailable.
