Abstract
A system and a method for the transmission and reception of digital data wirelessly using acoustic tones comprises a device having an encoder, a modulator system, a demodulator system, and a decoder. The modulator system uses dual tone multiple frequency (DTMF) tones that are amplitude modulated. The received signal is demodulated and detected by Fourier analysis. An expanded Hamming code based decoder is used for correcting errors occurring during transmission.
