Ergodic capacity analysis and transmission power optimization in D2D underlaying cellular communication [PDF]

, 2019
In this paper, we consider a non-cooperative deployment of Long Term Evolution (LTE) and Device-to-Device (D2D) links, for which we derive approximations for Signal-to-Interference and Noise Ratio (SINR) distributions plus ergodic capacity expressions ...

An Extensive Game-Based Resource Allocation for Securing D2D Underlay Communications

IEEE Access, 2019
Device-to-device (D2D) communication has been increasingly attractive due to its great potential to improve cellular communication performance. While resource allocation optimization for improving the spectrum efficiency is of interest in the D2D-related

Japanese Women's Attitudes Toward Learning Languages Other Than English in the Era of Global English

International Journal of Applied Linguistics, EarlyView.
ABSTRACT This study on female Japanese learners of the Korean language is situated in the centuries‐long anti‐Korean sentiments in Japan, the global popularity of the Korean Wave, particularly among women, and the essentialized image of socially marginalized young Japanese women who study English with romantic desires for Western men.

Teacher Well‐Being Across Career Stages: An Ecological Study of Early‐ and Mid‐Career English Teachers in Japanese Secondary Schools

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Teacher well‐being has garnered increasing attention in language education, as it plays a vital role in shaping both their professional lives and student learning. Although its importance is recognised, further research is still needed to gain a more comprehensive understanding of language teachers' well‐being.

Optimization of D2D emergency communication resources for UAV relay based on DA-STD3

EURASIP Journal on Wireless Communications and Networking
The allocation of communication resources is extremely important for the device-to-device (D2D) communication network with unmanned aerial vehicle (UAV) relays, but this field currently mainly focuses on the communication between UAVs and ground devices.

NOMA-Based D2D Communications: Towards 5G [PDF]

2016 IEEE Global Communications Conference (GLOBECOM), 2016
In this paper, a novel non-orthogonal multiple access (NOMA)-based device-to-device (D2D) communications framework is proposed. A major novelty of the proposed framework is that it introduces the new concept of ``D2D group" which utilizes NOMA transmission, enabling one D2D transmitter to communicate with multiple D2D receivers simultaneously. Based on

Measuring Interactional Competence in a Japanese University EFL Speaking Context

International Journal of Applied Linguistics, EarlyView.
ABSTRACT The ability to interact is an integral aspect of speaking proficiency. Therefore, methods of assessing interaction need to be incorporated into second language (L2) speaking tests. The main purpose of this exploratory study is to attempt to quantify interactional competence (IC) in a Japanese university EFL (English as a foreign language ...
