Performance Analysis of Orbital Angular Momentum (OAM): A 6G Waveform Design

Next-generation communication systems are required to be efficient in power and spectrum usage. In this direction, novel spatial multiplexing techniques, such as orbital angular momentum (OAM), contrast frequency multiplexing, orthogonal division (OFDM), regarded uphold potential advantages. This letter investigates OAM OFDM along with their emerging variants index modulation (IM) MIMO configuration. letter, these techniques implemented for different cell distances mainly single user cases. The bit error rate (BER) performance analysis is then carried out on a comparative scale. Moreover, Maximum likelihood least square-based receiver presented low complexity detection methods. strengths weaknesses of analyzed through extensive MATLAB simulations Signal-to-Noise Ratios (SNRs).
