IN-BAND MODEM SIGNALS FOR USE ON A CELLULAR TELEPHONE VOICE CHANNEL

摘要

Methods and systems for communicating data on a cellular telephone voice channel are disclosed. One method includes segmenting a data stream into one or more n-bit symbols (300); identifying a human vocal sound corresponding to each n-bit symbol according to a predetermined assignment of each n-bit symbol to a human vocal sound (302); and retrieving data representing the human vocal sound, wherein data representing the human vocal sound is configured to be passed through a vocoder (304).
