Robust Wideband Beamforming by the Hybrid Steepest Descent Method

open access: yesIEEE Transactions on Signal Processing, 2007
This paper uses the hybrid steepest descent method (HSDM) to design robust smart antennas. Several design criteria as well as robustness are mathematically described by a finite collection of closed convex sets in a real Euclidean space. Desirable beamformers are defined as points of the generalized convex feasible set which is well defined even in the

A Joint Scheduling and Millimeter Wave Hybrid Beamforming System with Partial Side Information [PDF]

open access: yes, 2016
The digital-analog hybrid beamforming technique with a number of antennas is necessary for the millimeter wave (mmWave) communications to overcome both high complexity of large array system and high path loss of mmWave signals.

Hybrid receive beamforming applied to ultrasound imaging [PDF]

open access: yes
In the field of ultrasound imaging, reducing the computational cost of image reconstruction (i.e., applying receive beamforming to multichannel transducer data) is important for practical system implementations.
