RIS-Assisted MIMO Communication Systems: Model-based versus Autoencoder Approaches
Ha An Le, Trinh Van Chien, Van Duc Nguyen +1
This paper considers reconfigurable intelligent surface (RIS)-assisted point-to-point multiple-input multiple-output (MIMO) communication systems, where a transmitter communicates…
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…
Polar-Cap Codebook Design for MISO Rician Fading Channels with Limited Feedback
Sung Hyuck Hong, Sucheol Kim, Junil Choi +1
Most of the prior works on designing codebooks for limited feedback systems have not considered the presence of strong line-of-sight (LOS) channel component. This paper proposes th…
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…
The Degrees of Freedom of the Interference Channel with a Cognitive Relay under Delayed Feedback
Hyo Seung Kang, Myung Gil Kang, Wan Choi +1
This paper studies the interference channel with a cognitive relay (ICCR) under delayed feedback. Three types of delayed feedback are studied: delayed channel state information at…
What Will 5G Be?
Jeffrey G. Andrews, Stefano Buzzi, Wan Choi +4
What will 5G be? What it will not be is an incremental advance on 4G. The previous four generations of cellular technology have each been a major paradigm shift that has broken bac…
