Deep Learning-Aided 5G Channel Estimation
An Le Ha, Trinh Van Chien, Tien Hoa Nguyen +2
Deep learning has demonstrated the important roles in improving the system performance and reducing computational complexity for G-and-beyond networks. In this paper, we propose…
On-off Switched Interference Alignment for Diversity Multiplexing Tradeoff Improvement in the 2-User X-Network with Two Antennas
Young-bin Kim, Myung Gil Kang, Wan Choi
To improve diversity gain in an interference channel and hence to maximize diversity multiplexing tradeoff (DMT), we propose on-off switched interference alignment (IA) where IA is…
Rate-Energy Region in Wireless Information and Power Transfer: New Receiver Architecture and Practical Modulation
Young-bin Kim, Dae Kyu Shin, Wan Choi
When simultaneous wireless information and power transfer is carried out, a fundamental tradeoff between achievable rate and harvested energy exists because the received power is u…
Optimal caching placement for wireless femto-caching network
Jaeyoung Song, Hojin Song, Wan Choi
This paper investigates optimal caching placement for wireless femto-caching network. The average bit error rate (BER) is formulated as a function of caching placement under wirele…
