Absolute localisation in confined spaces using deep geometric features
Electronics Letters, 2021 When operating in dark and confined spaces, the capacity of the robots to localise in an absolute reference frame is of utmost importance. This letter presents an absolute localisation system, using deep 3D landmarks, for known confined spaces.

On reconstruction methods for processing finite-length signals with paraunitary filter banks [PDF]
IEEE Transactions on Signal Processing, 1995 New expressions are developed for the perfect reconstruction of the boundary regions of a finite-length signal after subband processing. The time-invariant filter bank is required to be uniform and paraunitary, using FIR filters regardless of phase or symmetry.

Noise radar range doppler imaging via 2D generalized smoothed‐l0
Electronics Letters, 2021 This paper presents an algorithm to enhance the range‐Doppler imaging performance for noise radar. Traditional matched filtering based method suffers from high range and Doppler sidelobes, which makes the weak targets overwhelmed by the sidelobes of ...
