    • An improved time–frequency noise reduction method using a psycho-acoustic Mel model 

      Ouelha S.; Aïssa-El-Bey A.; Boashash B. ( Elsevier Inc. , 2018 , Article)
      This paper addresses the problem of noise reduction in non-stationary signals. The paper first describes a human physiology based time?frequency (TF) representation (HPTF) using Mel filterbanks. It is then used to improve ...

    • Time-frequency synthesis and filtering 

      Hlawatsch, F.; Matz, G.; Boashash, B.; Ouelha, S.; Stanković, S.; ... more authors ( Elsevier Inc. , 2016 , Book chapter)
      This chapter presents methods and techniques to design time-varying linear systems such as filters with precise time-frequency (t,f) specifications; this capability can then allow one to model and predict accurately the ...
