A low complexity downlink channel estimation method for high-speed mobile scenarios was proposed for the extra-large scale multiple-input multiple-output (MIMO) orthogonal time-frequency space (OTFS) system.Different from the existing studies, the pr

In this paper, we propose a low-complexity expectation propagation (EP) detector for orthogonal time frequency space (OTFS) system with practical rectangular waveforms. In the high-mobility scenario, OTFS is becoming a potential scheme for the sixth-

We study a parallel multi-access edge computing (MEC) system in this work and investigate its energy-efficient resources management. Particularly, the MEC system consists of an edge node and a number of mobile users, where each user has an inelastic

In this paper, we propose a low-complexity expectation propagation (EP) detector for extra-large scale massive multiple-input multiple-output (MIMO) systems. EP achieves the near-optimal performance in high-dimensional MIMO systems but suffers from t

Blind known self-interference cancellation (BKSC) is particularly attractive in self-interference (SI) reduction for full-duplex (FD) systems, because it requires no interference channel state information (CSI) and the overhead of capturing the full

In this letter, we investigate the transmit design for short-range multiple-input multiple-output (MIMO) channels with the spherical-wave model (SWM) in three-dimensional (3D) space. We first establish the antenna array with arbitrary orientations in
