Wireless-Comm.-of-RIS-assisted-Differential-Spatial-Modulation

This repository contains the modified MATLAB simulation code for the RIS-assisted Differential Transmitted Spatial Modulation (DTSM) scheme.

📖 Overview

The proposed DTSM scheme integrates the encoding process of differential spatial modulation (DSM) into a reconfigurable intelligent surface (RIS) assisted wireless communication system. At each time slot, only a single transmit antenna is activated to transmit an M-ary PSK symbol through the RIS.
