• Audio surveillance in unstructured environments

      Sharan, Roneel Vikash (Auckland University of Technology, 2015)
      This research examines an audio surveillance application, one of the many applications of sound event recognition (SER), and aims to improve the sound recognition rate in the presence of environmental noise using ...
    • Design of Sparse Antenna Array with Compressive Sensing

      Dong, Xin (Auckland University of Technology, 2018)
      As compared to single-element antenna, antenna array can not only achieve better radiation performance, but also be able to control the radiation beam. Aiming to achieve the same radiation performance, sparse antenna arrays ...
    • Single-channel Speech Enhancement Using Statistical Modelling

      Chehrehsa, Sarang (Auckland University of Technology, 2016)
      A new speech enhancement method based on Maximum A-Posteriori (MAP) estimation on Gaussian Mixture Models (GMMs) of speech and different noise types is introduced. The GMMs model the distribution of speech and noise ...
