Binary Polarization Shift Keying With Reconfigurable Intelligent Surfaces

We propose a novel binary polarization shift keying modulation scheme for line-of-sight environment by exploiting the control ability of reconfigurable intelligent surface (RIS). The RIS encodes information data in terms states either reflected wave from or composite wireless channel between an RF source and receiver. In first case, mismatch correction becomes essential at second pre-codes to compensate which allows non-coherent demodulation
