Abstract
In this letter, we employ quadrature spatial modulation (QSM) in both transmitter and receiver with the assistance of an intelligent reflecting surface (IRS), which we refer to as IRS-transceiver QSM (IRS-TQSM). In the compressive sensing (CS) framework, we cast the receiver processing as a sparsity recovery problem and propose a low-complexity algorithm by coupling the energy detector (ED) with convex programming (CP), referred to as ED-CP. The out-performance of the proposed IRS-TQSM with ED-CP compared to closely related works is demonstrated with numerical results.
