Low-Complexity Near-Field Channel Estimation for Hybrid RIS Assisted Systems
Rafaela Schroeder, Jiguang He, Hamza Djelouat +1
We investigate the channel estimation (CE) problem for hybrid RIS assisted systems and focus on the near-field (NF) regime. Different from their far-field counterparts, NF channels…
Hashing Beam Training for Near-Field Communications
Yuan Xu, Li Wei, Chongwen Huang +6
In this paper, we investigate the millimeter-wave (mmWave) near-field beam training problem to find the correct beam direction. In order to address the high complexity and low iden…
Stochastic Geometry Analysis for Distributed RISs-Assisted mmWave Communications
Yuan Xu, Li Wei, Chongwen Huang +6
Millimeter wave (mmWave) has attracted considerable attention due to its wide bandwidth and high frequency. However, it is highly susceptible to blockages, resulting in significant…
Coverage and Rate Analysis for Integrated Sensing and Communication Networks
Xu Gan, Chongwen Huang, Zhaohui Yang +6
Integrated sensing and communication (ISAC) is increasingly recognized as a pivotal technology for next-generation cellular networks, offering mutual benefits in both sensing and c…
On the Performance of LoRa Empowered Communication for Wireless Body Area Networks
Minling Zhang, Guofa Cai, Zhiping Xu +2
To remotely monitor the physiological status of the human body, long range (LoRa) communication has been considered as an eminently suitable candidate for wireless body area networ…
RIS-Enabled Anti-Interference in LoRa Systems
Zhaokun Liang, Guofa Cai, Jiguang He +3
It has been proved that a long-range (LoRa) system can achieve long-distance and low-power. However, the performance of LoRa systems can be severely degraded by fading. In addition…
