Impact of Antenna Configuration in Three-Dimensional Modulation Using Beam Hopping

Abstract

three-dimensional modulation using beam hopping (3DModBH) is a new transmission concept in long term evolution advanced (LTE-A) systems to improve system performance and increase its robustness against interference compared to state-of-the-art transmission scheme (SoAT). However, the presence of high user equipment (UE) density interference scenario in the cluster limits the performance of 3DModBH. The promised benefits of 3DModBH in such interference scenario disappear for the system configuration with four receive antennas, showing poorer performance than SoAT. The analytical and numerical results show that 3DModBH is capable to outperform the SoAT in high UE density interference scenario by increasing the number of receive antennas. Furthermore, it has been shown that the new concept achieves significant performance gain in high UE density interference than in low UE density interference scenario compared to SoAT.
