Webb25 juni 2024 · Blind identification was first applied on beamforming by using blind identification to estimate the steering vector without the prior knowledge of the array manifold . Based on the array structure, a blind beamforming method was proposed using estimating signal parameters via rotational invariance techniques (ESPRIT) to calculate … Webb4 jan. 2024 · We consider the problem of the joint design of transmit and receive beamforming (TRBF) vectors for integrated sensing and communication systems in the …
Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception. This is achieved by combining elements in an antenna array in such a way that signals at particular angles experience constructive interference while others experience destructive interference. Beamforming can be used at both the transmitting and receiving ends in order to achieve spatial selectivity. The improvement compar… http://www.ece.umn.edu/%7Enikos/GerSidShaBenOttSPMAG2010.pdf
