A pipeline structure for the block QR update in digital signal processing
Springer (2019-03)There exist problems in the field of digital signal processing, such as filtering of acoustic signals that require processing a large amount of data in real time. The beamforming algorithm, for instance, is a process that ... -
Fast block QR update in digital signal processing
Springer (2019-03)The processing of digital sound signals often requires the computation of the QR factorization of a rectangular system matrix. However, sometimes, only a given (and probably small) part of the system matrix varies from the ...
