Novel 3D Geometry-Based Stochastic Models for Non-Isotropic MIMO Vehicle-to-Vehicle Channels
Yi Yuan, Cheng-Xiang Wang, Xiang Cheng +2
This paper proposes a novel three-dimensional (3D) theoretical regular-shaped geometry-based stochastic model (RS-GBSM) and the corresponding sum-of-sinusoids (SoS) simulation mode…
Block-Wise Index Modulation and Receiver Design for High-Mobility OTFS Communications
Mi Qian, Fei Ji, Yao Ge +3
As a promising technique for high-mobility wireless communications, orthogonal time frequency space (OTFS) has been proved to enjoy excellent advantages with respect to traditional…
Estimating Doubly-Selective Channels for Hybrid mmWave Massive MIMO Systems: A Doubly-Sparse Approach
Shijian Gao, Xiang Cheng, Liuqing Yang
In mmWave massive multiple-input multiple-output (mMIMO) systems, hybrid digital/analog beamforming has been recognized as an economic means to overcome the severe mmWave propagati…
Flexible Energy Management Protocol for Cooperative EV-to-EV Charging
Rongqing Zhang, Xiang Cheng, Liuqing Yang
In this paper, we investigate flexible power transfer among electric vehicles (EVs) from a cooperative perspective in an EV system. First, the concept of cooperative EV-to-EV (V2V)…
