Low-Latency and Secure Computation Offloading Assisted by Hybrid Relay-Reflecting Intelligent Surface
Khac-Hoang Ngo, Nhan Thanh Nguyen, Thinh Quang Dinh +2
Recently, the hybrid relay-reflecting intelligent surface (HRRIS) has been introduced as a spectral- and energy-efficient architecture to assist wireless communication systems. In…
Transmit Correlation Diversity: Generalization, New Techniques, and Improved Bounds
Fan Zhang, Khac-Hoang Ngo, Sheng Yang +1
When the users in a MIMO broadcast channel experience different spatial transmit correlation matrices, a class of gains is produced that is denoted transmit correlation diversity.…
The Optimal DoF for the Noncoherent MIMO Channel with Generic Block Fading
Khac-Hoang Ngo, Sheng Yang, Maxime Guillaud
The high-SNR capacity of the noncoherent MIMO channel has been derived for the case of independent and identically distributed (IID) Rayleigh block fading by exploiting the Gaussia…
Joint Constellation Design for the Two-User Non-Coherent Multiple-Access Channel
Khac-Hoang Ngo, Sheng Yang, Maxime Guillaud +1
We consider the joint constellation design problem for the two-user non-coherent multiple-access channel (MAC). Based on an analysis on the non-coherent maximum-likelihood (ML) det…
Multi-User Detection Based on Expectation Propagation for the Non-Coherent SIMO Multiple Access Channel
Khac-Hoang Ngo, Maxime Guillaud, Alexis Decurninge +2
We consider the non-coherent single-input multiple-output (SIMO) multiple access channel with general signaling under spatially correlated Rayleigh block fading. We propose a novel…
Cube-Split: A Structured Grassmannian Constellation for Non-Coherent SIMO Communications
Khac-Hoang Ngo, Alexis Decurninge, Maxime Guillaud +1
In this paper, we propose a practical structured constellation for non-coherent communication with a single transmit antenna over Rayleigh flat and block fading channel without ins…
