A Pattern Modulation Based IRS Scheme for Space Shift Keying Communication System

In this letter, we propose a novel intelligent reflecting surface (IRS) aided receive generalized space shift keying (RGSSK) wireless communication scheme utilizing IRS reflection patterns to achieve high spectral efficiency transmission. In this scheme, additional bits are transmitted as a pattern information defined by the proposed group pattern strategy, while the IRS elements are divided for the RGSSK realization. Theoretical error performance is discussed with a joint maximum likelihood detector under the measurement of average bit error rate. Computer simulation results reveal the flexibility and reliability of this scheme with high spectral efficiency.
