Title:
METHOD, SYSTEM AND DATA SIGNAL DETECTOR FOR REALIZING DADA SERVICE
Document Type and Number:
WIPO Patent Application WO/2007/109960
Kind Code:
A1
Abstract:
A method for realizing data service in a voice band data manner comprises the following steps: a. a data signal detector divides the input signal frames into data signal frames and non-data signal frames, then a voice coder proceeds a voice coding on the data signal frames, while the non-voice coder proceeds a mute compression coding on the non-data signal frames; b. a voice decoder proceeds a voice decoding on the data signal frames which are voice coded to output available dada signals, while a non-voice decoder proceeds a decoding on the non-data signal frames which are mute compression coded to reconstruct mute signals. A system and a signal detector use this method.
