This paper studies the optimization of an active reconfigurable intelligent surface (RIS) under two power budget models. Two algorithms; one for each power constraint; for finding the optimal RIS configuration are proposed under the proviso that both the transmitter and receiver are equipped with a single antenna each. The computational complexities of these methods are linear in the number of RIS elements; and the resultant configurations are globally optimal. © 2002-2012 IEEE;
