Robust Adaptive Beamforming against Signal Steering Vector Mismatch and Jammer Motion
International Journal of Antennas and Propagation, 2015 Since adaptive beamformer suffers from output performance degradation in the presence of interference nonstationarity and signal steering vector mismatch, a novel robust null broadening adaptive beamforming is proposed. The proposed method is realized by

Diagonally-reinforced beam–column joints reinforced under cyclic loading [PDF]
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2005 The beam–column joints in a reinforced concrete frame are vulnerable to damage caused by seismic events. The conventional detailing using transverse hoops usually results in serious joint congestion, which creates contruction problems. This paper introduces a new detail especially developed for low to medium seismicity, which involves the use of ...

Adaptive beamforming for large arrays in satellite communications systems with dispersed coverage [PDF]
, 2011 Conventional multibeam satellite communications systems ensure coverage of wide areas through multiple fixed beams where all users inside a beam share the same bandwidth. We consider a new and more flexible system where each user is assigned his own beam,

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Approach of wideband robust adaptive beamforming based on microphone arrays
Tongxin xuebao, 2006 The approach of wideband robust adaptive beamforming （RABF） for speech enhancement based on micro-phone arrays was investigated. It combined the technologies of frequency focusing and diagonal loading, with the former aiming at frequency domain ...

Robust adaptive beamforming algorithm
Tongxin xuebao, 2009 The performance of least mean squares（LMS） algorithm degraded dramatically in the presence of even slight steering vector mismatches.In order to overcome the shortage,a novel robust adaptive beamforming algorithm based on the variable diagonal loading ...

Robust Recursive Algorithm under Uncertainties via Worst-Case SINR Maximization
Journal of Electrical and Computer Engineering, 2015 The performance of traditional constrained-LMS (CLMS) algorithm is known to degrade seriously in the presence of small training data size and mismatches between the assumed array response and the true array response.
