Narrowband Hybrid Beamformation System for Doable mmWave 5G Mobile Communication System

摘要

This paper introduces a new high-performance narrowband Hybrid Beamformation (HBF) system for upcoming mmWave-based 5G system. HBF system overcomes the pitfall of narrowband Analog only Beamformation and narrowband Digital only Beamformation. Next-generation 5G communication system will be taking the advantage of millimeter wave (mmWave) frequencies band that inherits signal fading and immense propagation loss. The move toward the mmWave spectrum facilitates the use of shorter wavelength. This facilitation makes possible for small antennas to focus its radiated signals into narrow beam to compensate for signal fading and path loss. An enhanced version of antenna gain with much focused antenna beam with HPBW of almost 11° with gain of 23.45 dB has been obtained in this paper. Assuming that both BS and MS have prior knowledge of the narrowband mmWave channel, we were able to achieve very low BER of almost zero when good signal strength was maintained after Beamformation.
