Radial basis function network assisted wide-band beamforming [PDF]
IEEE 60th Vehicular Technology Conference, 2004. VTC2004-Fall. 2004, 2005 In this paper, we present a novel radial basis function network (RBFN) assisted wide-band beamformer which is based on a derivation of the Bayesian detector. The proposed receiver structure significantly outperforms conventional linear wide-band beamformers in terms of the achievable angular resolution and thus the receiver is capable of supporting a ...

Joint Design of Transmitting Waveform and Receiving Filter via Novel Riemannian Idea for DFRC System
Remote Sensing, 2023 Recently, the problem of target detection in noisy environments for the Dual-Functional Radar Communication (DFRC) integration system has been a hot topic. In this paper, to suppress the noise and further enhance the target detection performance, a novel

Spherical harmonic covariance and magnitude function encodings for beamformer design [PDF]
EURASIP Journal on Audio, Speech, and Music Processing, 2021 AbstractMicrophone and speaker array designs have increasingly diverged from simple topologies due to diversity of physical host geometries and use cases. Effective beamformer design must now account for variation in the array’s acoustic radiation pattern, spatial distribution of target and noise sources, and intended beampattern directivity.

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,
