Abstract  Abstract

Systems and methods for providing improved adaptive multi-rate wideband (AMR-WB) discontinuous transmission (DTX) synchronization. According to various embodiments, an indicator related to the start of an inactive speech period can be detected in a predetermined number of frames before the start of a DTX period, i.e. a predetermined number of frames before receiving a SID_FIRST frame Voice activity detection (VAD) flag is delivered to the decoder. If the VAD flag indicates active speech, or if the VAD flag is set to zero more recently than a predetermined number of frames, the received NO_DATA frame can be reliably classified as active speech, i.e. It can be considered as signaling initiated by a transmitter, network, or terminal, and can be replaced with SPEECH_LOST. If the VAD flag is set to zero before 8 frames, the NO_DATA frame is classified as DTX. (Selection) Figure 1
