Feasibility of Orbital Angular Momentum for 6G Vehicular Communication

6th Generation (6G) wireless communications is expected to be rolled out in the early 2030s. Vehicular communications is expected to be an integral part of 6G. We test the feasibility of a proposed technology called Orbital Angular Momentum (OAM) to be used in this field. In this technology, a special twisted beam of electromagnetic waves is sent between transmitters and receivers to encode information in an extra dimension. This technology is well tested in laser technologies and short-range multimode optical fibres, but not in terahertz, high-mobility 6G vehicular scenarios. We develop a software frameowrk for assessing the feasibility of OAM channels in these scenarios and compare its performance with another commonly used technology called Orthogonal Frequency Division Multiplexing (OFDM). Through this, the thesis identifies the operating regimes where OAM is promising.
