Polar coded cooperative with Plotkin construction and quasi-uniform puncturing based on MIMO antennas in half duplex wireless relay network

ETRI Journal
Recently, polar code has attracted the attention of many scholars and has been developed as a code technology in coded-cooperative communication. We pro-pose a polar code scheme based on Plotkin structure and quasi-uniform punching (PC-QUP).

The impact of stressors on cognition during a survival exercise in polar waters—results of an experiment in northern Norway

As sea ice diminishes with global warming, new opportunities for commercial shipping, tourism and fishing arise in the polar regions in the winter. With this comes the risk of accidents.

Adaptations and lifestyle in polar marine environments: a biological challenge for the study of fish evolution

, 2004
The climatic features of Antarctic waters are more extreme and constant than in the Arctic. The Antarctic has been isolated and cold longer than the Arctic.

Adaptive Transmission Based on Polar Code and Hierarchical Modulation for Future Wireless Communications

IEEE Access
Polar codes are one of the most powerful types of forward error correction codes. These codes are now adopted in the 5G standard for control channels and are the primary contender for future communication systems.

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

Advanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Polar codes for channel and source coding

, 2009
The two central topics of information theory are the compression and the transmission of data. Shannon, in his seminal work, formalized both these problems and determined their fundamental limits. Since then the main goal of coding theory has been to find practical schemes that approach these limits.
