Abstract
A method for reflective index modulation based on intelligent reflecting surface, in which an IRS control unit is added into wireless communication system, and the data to be transmitted in a transmission is divided into two parts: a reflective domain data dand a phase-amplitude domain data d, the reflective domain data dis transmitted through a wired connection to the IRS control unit to activate or deactivate each group of reflecting elements, the phase-amplitude domain data dis modulated through traditional phase-amplitude domain modulation and transmitted to the IRS, the reflected signals contain the information of the reflective domain data d, through the demodulating the baseband symbol y, an estimated phase-amplitude modulation indexand an estimated reflective indexare obtained to recover the phase-amplitude domain data dand the value of the reflective domain data drespectively.
