Joint Active Beamforming Design and Performance Analysis for Active RIS-Aided Cognitive Multigroup Multicast Systems

This paper considers design optimization for an active reconfigurable intelligent surface (active RIS)-aided cognitive multigroup multicast communication system. To minimize the sum of the weighted power of the cognitive radio base station (CRBS) and active RIS, the joint design problem of CRBS matr...
