Beampattern Gain Optimization for Near-Field Wideband Multi-User ISAC Systems

With the help of large-scale antenna arrays and sufficient bandwidth, integrated sensing and communication (ISAC) system can provide high-rate communications and high-accuracy target sensing. However, such ISAC system may experience near-field propagation and severe beam squint effects, which makes the beamforming desi...

2D Movable Antenna Assisted ISAC: Joint Beamforming and Antenna Position Optimization

This paper studies a two-dimensional (2D) movable-antenna (MA) assisted integrated sensing and communications (ISAC) system. The base station serves multiple single-antenna users and senses one point target using a reconfigurable 2D MA array. The considered design exploits antenna-position adaptation and transmit beamf...

Traffic-Aware Joint Clustering and Routing in Energy-Harvesting Industrial Internet of Things

The energy-harvesting industrial IoT networks exhibit intertwined quasi-periodic dynamics in traffic patterns and energy budgeting. However, conventional myopic approaches optimize only instantaneous states, resulting in a mismatch between traffic demand and energy supply. To address this, we present a traffic-aware jo...
