The decomposition tree structure of PWPT is designed to approximate the critical bands (CB) as close as possible in order to efficiently match the psychoacoustic model [12] [13].
They also explored other methods focused on masking the musical noise using psychoacoustic models [6]; results obtained by using these algorithms show that there is a need for further improvement in the radar speech enhancement algorithm, especially at a very low SNR condition (SNR < 10 dB).
