| Zusammenfassung: | The embodiment of the invention discloses a method and device for determining inband signalling decoding mode, relating to the communication field and improving accuracy rate of inband signalling decoding. The invention includes: probabilities of all decoding modes of inband signalling in signal received at preset moment are calculated by utilizing posterior probability algorithm; according to the calculated probabilities of decoding modes, the decoding mode the probability of which is maximal is selected as the decoding mode of inband signalling in the signal received at preset moment. The embodiment of the invention is mainly used in the process for determining decoding mode of inband signalling in speech frame transmission process. |
