Interference-Based Decode and Forward Scheme Using Relay Nodes in Heterogeneous Networks
International Journal of Antennas and Propagation, 2012 This paper proposes interference-based decode and forward scheme that utilizes relay stations (RSs). In Long-Term-Evolution (LTE-) Advanced, heterogeneous networks in which femto- and picocells are overlaid onto macrocells are extensively discussed ...

A Hybrid Cooperative Coding Scheme for the Relay-Eavesdropper Channel
Entropy, 2014 This paper considers the four-node relay-eavesdropper channel, where a relay node helps the source to send secret messages to the destination in the presence of a passive eavesdropper.

Flow Decomposition for Multi-User Channels - Part I
, 2018 A framework based on the idea of flow decomposition is proposed to characterize the decode-forward region for general multi-source, multi-relay, all-cast channels with independent input distributions. The region is difficult to characterize directly when

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced 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.

Cooperative Spectrum Sensing Schemes with the Interference Constraint in Cognitive Radio Networks
Sensors, 2014 In this paper, we propose cooperative spectrum sensing schemes, called decode-and-forward cooperative spectrum sensing (DF-CSS) scheme and amplify-and-forward cooperative spectrum sensing (AF-CSS) scheme, in cognitive radio networks.

Advanced Robotics Research, EarlyView.A miniaturized soft optical sensor that uses thin film color tuning enables real‐time 3D shape‐sensing from a single red–green–blue (RGB) signal. When integrated into a soft robot, it enables closed‐loop control and autonomous navigation in a phantom lung environment without the need for onboard electronics, achieving sub‐millimeter accuracy through ...

Packet-Level Modeling of Cooperative Diversity: A Queueing Network Approach
IEEE Access, 2018 Cooperative communications are expected to be a centerpiece for 5G cellular networks. Using cooperation, a wider and more uniform network coverage is attained, network capacity is enhanced, and power consumption is drastically reduced. While these latter

Relays for Interference Mitigation in Wireless Networks [PDF]
, 2010 Wireless links play an important role in the last mile network connectivity. In contrast to the strictly centralized approach of today's wireless systems, the future promises decentralization of network management.

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...
