Reconfigurable Intelligent Surface-Assisted Space Shift Keying [PDF]

IEEE Wireless Communications Letters, 2020
The concept of reconfigurable intelligent surface (RIS)-assisted transmission, where phases of reflected signals are adjusted in an effective arrangement, has been recently put forward as a promising solution for 6G and beyond networks. Considering this and the undeniable potential of index modulation (IM) techniques, an RIS-based space shift keying ...

Reconfigurable Intelligent Surfaces: Channel Characterization and Modeling

Proceedings of the IEEE, 2022
Reconfigurable intelligent surfaces (RISs) are two dimensional (2D) metasurfaces which can intelligently manipulate electromagnetic waves by low-cost near passive reflecting elements. RIS is viewed as a potential key technology for the sixth generation (6G) wireless communication systems mainly due to its advantages in tuning wireless signals, thus ...

Integrated reconfigurable control and guidance based on evaluation of degraded performance [PDF]

, 2016
The present paper is focused on analysing an integrated reconfigurable control and guidance approach for recovering a small fixed-wing UAV from different actuator faults, which cover locked in place (stuck) and loss of effectiveness. The model of the UAV

Active Reconfigurable Intelligent Surface-Aided Wireless Communications

IEEE Transactions on Wireless Communications, 2021
Reconfigurable Intelligent Surface (RIS) is a promising solution to reconfigure the wireless environment in a controllable way. To compensate for the double-fading attenuation in the RIS-aided link, a large number of passive reflecting elements (REs) are conventionally deployed at the RIS, resulting in large surface size and considerable circuit power ...
