Claim 0:
1. A method for communicating data acoustically, comprising:
segmenting the data into a sequence of symbols, each of the symbols having a preset number of bits;
determining for each symbol of the sequence of symbols a plurality of tones based on a bijective mapping between symbols and sets of tones selected from tones spread evenly over a frequency spectrum, wherein each set of tones among the sets of tones includes a same number of tones and each of the plurality of tones for each symbol in the sequence of symbols is at a different frequency; and
for each symbol in the sequence of symbols, simultaneously acoustically generating, using a speaker, the plurality of tones determined for the respective symbol,
wherein the bijective mapping includes a mapping between the symbols and a multi-tone Frequency Shift Keying signal including the plurality of tones.
