A Novel Beamforming Algorithm for GNSS Receivers with Dual-Polarized Sensitive Arrays in the Joint Space–Time-Polarization Domain

open access: yesSensors, 2018
Dual-polarized sensitive arrays (DPSAs) with the space⁻time-polarization adaptive processing (STPAP) technique, which employs the polarization domain as well as the space domain and time domain to filter out interferences, can cancel a larger ...

Adaptive beamforming for quadrupole resonance

open access: yesDigital Signal Processing, 2007
We present several adaptive beamforming approaches to improve the quadrupole resonance (QR) signal detection performance via exploiting both the spatial and temporal correlation of radio frequency interferences (RFIs). We operate in the framework of signal amplitude estimation with known signal waveform and make use of three adaptive beamforming ...

An Approximate Algorithm for Robust Adaptive Beamforming [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2004
Summary: This paper presents an adaptive weight computation algorithm for a robust array antenna based on the sample matrix inversion technique. The adaptive array minimizes the mean output power under the constraint that the mean square deviation between the desired and actual responses satisfies a certain magnitude bound.
