1. A method for waveform transmission, the method comprising:

  • receiving a plurality of information symbols;

    creating a matrix of modulation parameters by using each of the plurality information symbols to modulate one of a plurality of two-dimensional basis functions on a time-frequency plane wherein each of the plurality of two-dimensional basis functions is uniquely associated with one of the plurality of information symbols;

    generating a transmit waveform comprised of a plurality of pulse waveforms, each of the plurality of pulse waveforms corresponding to a combination of one of the modulation parameters and one of a plurality of time-translated and frequency-modulated versions of a fundamental transmit pulse; and

    transmitting the transmit waveform over a communication channel.
