Information Bottleneck for a Rayleigh Fading MIMO Channel with an Oblivious Relay

open access: yesInformation, 2021
This paper considers the information bottleneck (IB) problem of a Rayleigh fading multiple-input multiple-out (MIMO) channel with an oblivious relay. The relay is constrained to operating without knowledge of the codebooks, i.e., it performs oblivious ...

Relay Channels with Unreliable Helpers

open access: yes2023 IEEE International Symposium on Information Theory (ISIT), 2023
The relay channel with unreliable helper is introduced and studied. The model is that of a classical relay channel where the input from the relay to the channel has an extra primitive link whose presence is not assured a priori. The extra link represents a helper who may decide not to cooperate in transmission.

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.

Beamforming for Dual-Hop MIMO AF Relay Networks With Channel Estimation Error and Feedback Delay

open access: yesIEEE Access, 2017
This paper concerns the beamforming (BF) design for a dual-hop multiple-input multiple-output (MIMO) amplify-and-forward (AF) relay network. Both a general antenna configuration and imperfect channel state information are taking into consideration, where

A Relay Selection Method for Battery-dependent Relay Nodes [PDF]

open access: yesJisuanji gongcheng, 2017
Due to the fast power consumption and even the reduction of network lifetime caused by the frequent data forwarding for the battery-dependent relay nodes with higher channel qualities in collaborative communication network,a relay selection method is ...

Combining coded signals with arbitrary modulations in orthogonal relay channels [PDF]

open access: yes, 2008
We consider a relay channel for which the following assumptions are made. (1) The source-destination and relay-destination channels are orthogonal (frequency division relay channel). (2) The relay implements the decode-and-forward protocol.
