A Novel RIS-Assisted Modulation Scheme [PDF]
IEEE Wireless Communications Letters, 2021 In this work, in order to achieve higher spectrum efficiency, we propose a reconfigurable intelligent surface (RIS)-assisted multi-user communication uplink system. Different from previous work in which the RIS only optimizes the phase of the incident users's signal, we propose the use of the RIS to create a virtual constellation diagram to transmit ...

Endotrivial modules for finite group schemes [PDF]
Journal für die reine und angewandte Mathematik (Crelles Journal), 2011 It is well known that if G is a finite group then the group of endotrivial modules is finitely generated. In this paper we investigate endotrivial modules over arbitrary finite group schemes. Our results can be applied to computing the endotrivial group for several classes of infinitesimal group schemes which include the Frobenius kernels of parabolic ...

Time Reversal UWB Communication System: A Novel Modulation Scheme with Experimental Validation
EURASIP Journal on Wireless Communications and Networking, 2010 A new modulation scheme is proposed for a time reversal (TR) ultra wide-band (UWB) communication system. The new modulation scheme uses the binary pulse amplitude modulation (BPAM) and adds a new level of modulation to increase the data rate of a TR UWB ...
