Robust beamforming method for SDMA with interleaved subarray hybrid beamforming
2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2016This paper considers millimeter-wave access network systems with space division multiple access using an interleaved subarray hybrid beamforming structure, where antenna elements in each subarray scatter uniformly over the whole antenna array. The structure can provide high system capacity by multiplexing users in the space domain with narrow beams ...

Millimeter-Wave NOMA with Hybrid Beamforming
2019 IEEE International Conference on Communications Workshops (ICC Workshops), 2019This paper investigates the application of nonorthogonal multiple access in millimeter-Wave communications (mmWave-NOMA) with hybrid beamforming. A user grouping algorithm is first proposed according to channel gains and channel correlations. Whereafter, a joint hybrid beamforming and power allocation problem is formulated to maximize the achievable ...

Hybrid beamforming: reduced eigen beamforming on beam signals
2002 International Zurich Seminar on Broadband Communications Access - Transmission - Networking (Cat. No.02TH8599), 2003A hybrid beamforming technique for multiple antenna receivers is introduced. It is a combination of a simple fixed beam method and the adaptive eigen beamforming algorithm. This two-stage solution allows for a user-specific scalable trade-off between performance and complexity, depending on the interference scenario.

Hybrid analog digital beamforming
2022In recent years, two of the main trends in wireless communication have been higher carrier frequencies and larger antenna arrays. Each trend by itself allows for a significant gain in system performance, but they are difficult to combine. The former trend, higher carrier frequencies in the millimeter-wave (mm-wave) range, offers an unprecedented ...

Online Channel Estimation for Hybrid Beamforming Architectures
ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020Hybrid analog-/digital beamforming architectures are a promising means of reducing power consumption and hardware costs in large multi-antenna transceivers. However, channel estimation becomes more complicated compared with conventional (fully-digital) architectures because multiple measurements (pilots in subsequent time slots) are required to ...

Hybrid Beamforming Design for ITS-Assisted Wireless Networks
IEEE Wireless Communications Letters, 2023This letter proposes a hybrid beamforming design for an intelligent transmissive surface (ITS)-assisted transmitter wireless network. We aim to suppress the sidelobes and optimize the mainlobes of the transmit beams by minimizing the proposed cost function based on the least squares (LS) for the digital beamforming vector of the base station (BS) and ...

Quantization error reduction scheme for hybrid beamforming
2012 18th Asia-Pacific Conference on Communications (APCC), 2012In a multiple-input multiple-output (MIMO) system of a large number of antennas, the requirement of an analog to digital converter (ADC) in each antenna string causes high implementation cost and excessive signal processing. Hence, a hybrid beamforming has been proposed in the literature as a solution.

New Predistorter Architecture for Hybrid Beamforming Transmitter
2020 IEEE 92nd Vehicular Technology Conference (VTC2020-Fall), 2020In this paper, we propose a novel subarray digital predistorter (DPD) with timely shared feedback for hybrid beamforming transmitters. This enables a set of power amplifiers (PAs) to be linearized with a single DPD. The output signal in the proposed DPD comprises the weighted combination of the inverse functions of the individual PAs from an array ...

Hybrid adaptive/nonadaptive beamforming for ultrasound imaging
2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013We propose and evaluate a simple yet effective technique of combining nonadaptive and adaptive beamforming methods aimed to achieve high quality of ultrasound images at low computational cost. Our hybrid beamformer automatically switches between nonadaptive and adaptive beamforming of input data vectors, based on the outcome of the comparison of the ...
