Abstract
Hybrid beamforming which combines conventional digital beamforming with analog beamforming system is promising model in wireless communication. The problem is using RF chain in digital precoder spends high cost and variable phase shifter exist at analog precoder processing network. Dealing with this problem, many architectures emerge to make lower hardware complexity and power consumption. This paper proposes low-resolution solution using phase over-sampling(POS) and switches(SW) on Radio Frequency(RF) chain to improve energy efficiency. We analyze proposed POS-SW hybrid beamforming system. In the simulation, the estimate is channel capacity in different signal-to-noise and energy efficiency during increasing number of RF chain on 3 dimension(3D) channel environment. It is shown that the proposed system has almost same channel capacity and high energy efficiency compared to the conventional system.
