Sparse Multipath Channel Estimation and Decoding for Broadband Vector OFDM Systems
Qi Feng, Xiang-Gen Xia, Zhihui Ye +1
Vector orthogonal frequency division multiplexing (V-OFDM) is a general system that builds a bridge between OFDM and single-carrier frequency domain equalization in terms of inters…
Artificial-Noise-Aided Message Authentication Codes with Information-Theoretic Security
Xiaofu Wu, Zhen Yang, Cong Ling +1
In the past, two main approaches for the purpose of authentication, including information-theoretic authentication codes and complexity-theoretic message authentication codes (MACs…
Iterative Eigenvalue Decomposition and Multipath-Grouping Tx/Rx Joint Beamforming for Millimeter-Wave Communication
Zhenyu Xiao, Xiang-Gen Xia, Depeng Jin +1
We investigate Tx/Rx joint beamforming in millimeter-wave communications (MMWC). As the multipath components (MPCs) have different steering angles and independent fadings, beamform…
Hierarchical Codebook Design for Beamforming Training in Millimeter-Wave Communication
Zhenyu Xiao, Tong He, Pengfei Xia +1
In millimeter-wave communication, large antenna arrays are required to achieve high power gain by steering towards each other with narrow beams, which poses the problem to efficien…
A Robust Generalized Chinese Remainder Theorem for Two Integers
Xiaoping Li, Xiang-Gen Xia, Wenjie Wang +1
A generalized Chinese remainder theorem (CRT) for multiple integers from residue sets has been studied recently, where the correspondence between the remainders and the integers in…
Pilot Reuse for Massive MIMO Transmission over Spatially Correlated Rayleigh Fading Channels
Li You, Xiqi Gao, Xiang-Gen Xia +2
We propose pilot reuse (PR) in single cell for massive multiuser multiple-input multiple-output (MIMO) transmission to reduce the pilot overhead. For spatially correlated Rayleigh…
