1. An acoustic data transmission method for enhancing signal quality of a transmitted signal comprising:

  • identifying desired signal qualities;

    generating a first acoustic signal generated using a first waveform, a first mode and a first power,transmitting the first acoustic signal into a formation;

    receiving the first acoustic signal at a plurality of receivers;

    computing formation velocities from data extracted from the first acoustic signal;

    computing signal qualities of the first acoustic signal;

    identifying an error calculation between the first acoustic signal qualities and the desired signal qualities;

    performing an optimization of a plurality of parameters using information from a plurality of sensors regarding formation characteristics and the formation velocities extracted from the first acoustic signal, wherein the optimization generates an optimum second waveform, an optimum second transmission mode and optimum second power;

    generating a second acoustic signal using the optimum second waveform, second transmission mode and second power.
