Secure Communication for Spatially Sparse Millimeter-Wave Massive MIMO Channels via Hybrid Precoding
Jindan Xu, Wei Xu, Derrick Wing Kwan Ng +1
In this paper, we investigate secure communication over sparse millimeter-wave (mm-Wave) massive multiple-input multiple-output (MIMO) channels by exploiting the spatial sparsity o…
Deep Learning Assisted Sum-Product Detection Algorithm for Faster-than-Nyquist Signaling
Bryan Liu, Shuangyang Li, Yixuan Xie +1
A deep learning assisted sum-product detection algorithm (DL-SPA) for faster-than-Nyquist (FTN) signaling is proposed in this paper. The proposed detection algorithm concatenates a…
Physical Layer Security for Ultra-Reliable and Low-Latency Communications
Riqing Chen, Chunhui Li, Shihao Yan +2
Ultra-reliable and low-latency communication (URLLC) is one category of service to be provided by next-generation wireless networks. Motivated by increasing security concerns in su…
Density Evolution Analysis of Partially Information Coupled Turbo Codes on the Erasure Channel
Min Qiu, Xiaowei Wu, Yixuan Xie +1
In this paper, we investigate the performance of a class of spatially coupled codes, namely partially information coupled turbo codes (PIC-TCs) over the binary erasure channel (BEC…
Downlink Non-Orthogonal Multiple Access without SIC for Block Fading Channels: An Algebraic Rotation Approach
Min Qiu, Yu-Chih Huang, Jinhong Yuan
In this paper, we investigate the problem of downlink non-orthogonal multiple access (NOMA) over block fading channels. For the single antenna case, we propose a class of NOMA sche…
A Two-Stage Beam Alignment Framework for Hybrid MmWave Distributed Antenna Systems
Zhiqiang Wei, Min Qiu, Derrick Wing Kwan Ng +1
In this paper, we investigate the beam alignment problem in millimeter-wave (mmWave) distributed antenna systems where a home base station communicates with multiple users through…
