摘要：
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 a plurality of acoustical tones with a fundamental frequency and multiple harmonics that are amplitude modulated. The received signal is demodulated and detected by quadrature detectors comprising replicas of the acoustical tones. An extended Golay code based decoder is used for correcting errors occurring during transmission.
