Secure lossless transmission of correlated sources over noisy broadcast channel using separate source-channel coding

open access: yesTongxin xuebao, 2013
The problem of secure transmission of correlated sources over broadcast channel was studied from the pers-pective of information-theoretic security.Each source is only for its intended receiver,but to be kept secret from the un-intended receiver ...

Gaussian broadcast channel with lossy state reconstruction

open access: yesDigital Communications and Networks, 2019
We consider a state reconstruction problem where the additive state process of a Gaussian Broadcast Channel (GBC) is to be reconstructed at both receivers, subject to some distortion constraints.

Improving Broadcast Channel Rate Using Hierarchical Modulation [PDF]

open access: yes, 2012
We investigate the design of a broadcast system where the aim is to maximise the throughput. This task is usually challenging due to the channel variability.

Broadcast channel simulation [PDF]

open access: yes, 2023
We study the problem of random-assisted simulation of discrete broadcast channel in one-shot and i.i.d. setups. We derive one-shot inner and outer bounds of the set of attainable message-size pairs for simulating W YZ|X within some total variation ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation

open access: yesAdvanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Secure transmission of correlated sources over broadcast channels with ultra-low latency

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
Correlated sources passing through broadcast channels is considered in this paper. Each receiver has access to correlated source side information and each source at the sender is kept secret from the unintended receiver.

Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

open access: yesAdvanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment
