UAV and Vehicular Communication with Hardware Impairments in Multiple RIS System

Abstract

In Vehicle-to-vehicle communication the Tera hertz band communication is not suitable as it affects health and RIS is the hopeful technique. This paper suggests a UAV to UAV or UAV to base station type of communication and its determining parameters under hardware constituting its errors. The position-based information is taken as a data source to avoid doppler effect and also spectrally efficient under a high-speed communication at hardware problems. This also aids the multi-RIS system. The proposed method upsurges the spectral efficiency for increasing the multi-RIS based communication. Comparisons are based on optimization of diverse phase shift with maximum spectral efficiency based on the power control. The proposed method eliminates the doppler spread. The delay spread is quite little possible and it can also be further more decreased by the using novel form of signal like delay-doppler modulation technique that utilizes a two-dimensional waveform. Simulation results show that increasing the number of IRS elements in each IRS gives a better spectral efficiency.
