Our goal is to use Discrete Multi-Tone modulation to transmit a text message over the audible range of frequencies in an acoustic channel. We are creating a DSL modem that transmits through the air.
To do this, we will observe the frequency characteristics of the channel, and use that information to equalize our received transmission in hope to preserve the maximum amount of content from the signal. As in any engineering problem, we are constantly striving to push the data-rate of our system, while minimizing the occurrence of errors. Here we go!
