    • Accurate and efficient implementation of the time–frequency matched filter 

      O'Toole, J.M.; Mesbah, M; Boashash, B ( Institution of Engineering and Technology , 2010 , Article)
      The discrete time-frequency matched filter should replicate the continuoustime-frequency matched filter, but the methods differ. To avoid aliasing, thediscrete method transforms the real-valued signal to the complex-valued ...

    • Improved Discrete Definition of Quadratic Time-Frequency Distributions 

      O'Toole, J.M.; Mesbah, M.; Boashash, B. ( IEEE , 2010 , Article)
      Computation of a time-frequency distribution (TFD) requires a discrete version of the continuous distribution. This discrete TFD (DTFD) should be free from aliasing and conserve all the important mathematical properties ...

    • Multiple-view time-frequency distribution based on the empirical mode decomposition 

      Stevenson, N.J; Mesbah, M; Boashash, B ( Institution of Engineering and Technology , 2010 , Article)
      This study proposes a novel, composite time-frequency distribution (TFD) constructed using a multiple-view approach. This composite TFD utilises the intrinsic mode functions (IMFs) of the empirical mode decomposition (EMD) ...
