Abstract
Methods and systems for improved transmission and receipt of audio transmissions containing data encoded according to different protocols are presented. In one embodiment, a method is provided that includes receiving a digital data bitstream containing data for transmission using an audio transmission. The digital data bitstream may be divided into a plurality of symbols (e.g., according to a type of encoding protocol to be used). An analog audio signal may be generated that encodes the plurality of symbols according to an encoding protocol (e.g., a PSK protocol and/or a DPSK protocol). The analog audio signal may be added to the audio transmission and the audio transmission may be transmitted using an audio transmitter.
