Joint Rate Allocation and Power Control for RSMA-Based Communication and Radar Coexistence Systems
Trung Thanh Nguyen, Nguyen Cong Luong, Shaohan Feng +4
We consider a rate-splitting multiple access (RSMA)-based communication and radar coexistence (CRC) system. The proposed system allows an RSMA-based communication system to share s…
Deep Learning-Based Signal Detection for Dual-Mode Index Modulation 3D-OFDM
Dang-Y Hoang, Tien-Hoa Nguyen, Vu-Duc Ngo +3
In this paper, we propose a deep learning-based signal detector called DuaIM-3DNet for dual-mode index modulation-based three-dimensional (3D) orthogonal frequency division multipl…
An Analysis of Uplink Success Probability in Multi-Cell Lora Networks Under Different Channel Models
Tien Hoa Nguyen, Van Dai Do
The development of the low power wide area network (LPWAN) for the internet of things (IoTs) is expected to grow widely, allowing remote monitoring of smart devices from a distance…
Pilot Assignment for Joint Uplink-Downlink Spectral Efficiency Enhancement in Massive MIMO Systems with Spatial Correlation
Tien Hoa Nguyen, Trinh Van Chien, Hien Quoc Ngo +2
This paper proposes a flexible pilot assignment method to jointly optimize the uplink and downlink data transmission in multi-cell Massive multiple input multiple output (MIMO) sys…
Impact of Inter-Channel Interference on Shallow Underwater Acoustic OFDM Systems
Do Viet Ha, Tien Hoa Nguyen, Van Duc Nguyen
This paper investigates the impacts of Inter-Channel Interference (ICI) effects on a shallow underwater acoustic (UWA) orthogonal frequency-division multiplexing (OFDM) communicati…
