Ultra-High Resolution Method for Multipath Within a Co-Delay-Doppler Bin in DFT-P-OCDM
Mingxuan Han, Weile Zhang, Feifei Gao
Communication systems can reuse their transmitted signals for sensing without dedicated radar transmissions. For an established DFT-preprocessed orthogonal chirp division multiplex…
Sphere Decoding Revisited
Zheng Wang, Cong Ling, Shi Jin +2
In this paper, the paradigm of sphere decoding (SD) for solving the integer least square problem (ILS) is revisited, where extra degrees of freedom are introduced to exploit the de…
Model-Driven Deep Learning for Non-Coherent Massive Machine-Type Communications
Zhe Ma, Wen Wu, Feifei Gao +2
In this paper, we investigate the joint device activity and data detection in massive machine-type communications (mMTC) with a one-phase non-coherent scheme, where data bits are e…
Hierarchical Codebook Design for Near-Field MmWave MIMO Communications Systems
Jiawei Chen, Feifei Gao, Mengnan Jian +1
Communications system with analog or hybrid analog/digital architectures usually relies on a pre-defined codebook to perform beamforming. With the increase in the size of the anten…
Electromagnetic Channel Model for Near Field MIMO Systems in The Half Space
Yuhua Jiang, Feifei Gao
In most multiple-input multiple-output (MIMO) communication systems, the amount of information that can be transmitted reliably depends on the effective degrees of freedom (EDoF) o…
Joint Precoding for Active Intelligent Transmitting Surface Empowered Outdoor-to-Indoor Communication in mmWave Cellular Networks
Xie Xie, Chen He, Feifei Gao +2
Outdoor-to-indoor communications in millimeter-wave (mmWave) cellular networks have been one challenging research problem due to the severe attenuation and the high penetration los…
