Background: The multiuser scenarios using the recently proposed wireless communication scheme, namely Beam Index Modulation (BIM), are investigated in this paper. Methods: Both transmitter node and multiple receiver nodes are equipped with analogue beamforming networks, transforming physical wireless propagation channels to virtue channels in beam domain. Results: Under the non-line-of-sight (nLoS) multi-scatterer channel conditions, which are likely the cases for some future wireless communication systems operating at higher frequency bands. Conclusion: It has been proved, both through simulations and experiment, at 10 GHz in an indoor environment, that the proposed BIM is able to enhance the system performance at high Signal-to-Noise Ratio (SNR) scenarios, with regard to the sum spectral efficiency, with only a single Radio Frequency (RF) chain.

Keywords: Analogue beamforming, beam index modulation, index modulation, multiuser
