Rate Loss of Hybrid Beamforming with Imperfect Phase Shifters in Millimeter Wave Systems
In millimeter massive MIMO systems, hybrid beamforming algorithms with fewer RF chain are widely applied as they can save power and cut down on hardware costs. Hybrid beamforming can be divided into two stages: analog beamforming in the RF domain usually implemented with phase shifters and digital beamforming in the baseband domain. Phase shifters have rms phase error and rms gain error which a...
متن کاملHybrid Beamforming with Reduced Number of Phase Shifters for Massive MIMO Systems
In this paper, two novel hybrid beamforming methods are proposed to reduce the cost and power consumption of hybrid beamformers with subconnected phase shifter network structure in massive multiple-input multiple-output (MIMO) systems. This is achieved by replacing some of the phase shifters with switches which, in general, are cheaper and have lower power consumption compared to phase shifters...
متن کاملHybrid Analog-Digital Beamforming: How Many RF Chains and Phase Shifters Do We Need?
This paper considers hybrid beamforming (HB) for downlink multiuser massive MIMO systems with frequency selective channels. For this system, first we quantify the required number of radio frequency (RF) chains and phase shifters (PSs) such that the proposed HB achieves the same performance as that of the digital beamforming (DB) which utilizes N (number of transmitter antennas) RF chains. We sh...
متن کاملHybrid Precoder and Combiner Design with Low Resolution Phase Shifters in mmWave MIMO Systems
Millimeter wave (mmWave) communications have been considered as a key technology for next generation cellular systems and Wi-Fi networks because of its advances in providing orders-of-magnitude wider bandwidth than current wireless networks. Economical and energy-efficient analog/digial hybrid precoding and combining transceivers have been often proposed for mmWave massive multiple-input multip...
متن کاملEnergy Efficient Wireless Communication using Distributed Beamforming
Energy Efficient Wireless Communication using Distributed Beamforming by Raghuraman Mudumbai We consider the use of distributed beamforming to improve the energy efficiency and transmission range of wireless networks. Under distributed beamforming, a number of wireless transmitters collaboratively transmit a common message signal in such way that their individual transmissions combine coherentl...
