Abstract: Pitch estimation and classification into voiced, unvoiced and transitional speech were performed by a spectro-temporal auto-correlation technique. A peak picking formula was then employed. A weighing function was then applied to the power spectrum. The harmonics weighted power spectrum underwent mel-scaled band-pass filtering, and the log-energy of the filter's output was discrete cosine transformed to produce cepstral coefficients. A within-filter cubic-root amplitude compression was applied to reduce amplitude variation without compromise of the gain invariance properties.

Abstract: A method for a terminal to join a multicast broadcast service (MBS) in a wireless network and a wireless communication system are provided, so as to enable a terminal to successfully join an MBS and receive MBS content. The method and the system relate to a wireless communication field.

The terminal may initiate an MBS join process by sending an MBS join request message, so as to obtain the MBS parameters and join the required MBS. The network may actively initiate the MBS join process to send the MBS parameters to the terminal and invite the terminal to join the MBS.
