Abstract
Some embodiments relate to systems and methods for communication of electronic signals. An example method includes receiving a first signal having a predetermined modulation. The example method includes generating a transmission for a second signal by superimposing the second signal on the modulation of the first signal by adjusting at least one of two phase states or two amplitude states of the modulation using a Reconfigurable Intelligent Surface (RIS). The example method also includes transmitting the second signal using hierarchical modulation, the predetermined modulation and the superimposed second signal on the predetermined modulation, wherein the first signal is transmitted at a higher data rate than the second signal.
