Dual-Beam Analog Beamforming for mmWave Communications (original) (raw)

Abstract

Conventional initial beam access schemes for millimeter wave systems suffer from high computational complexity and prolonged access times. Hence this paper proposes an efficient beam access algorithm based upon simultaneous dual-beam codebook transmission and beam coding. The spatial search space is formulated as an optimization problem and a novel direct-pattern search is proposed here, i.e., the algorithm adapts the beam search by conquering the observed cluster profile. Simulation results show that the algorithm significantly overcomes major access methods.
