Abstract

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