1. A method for transmitting data in a wireless network, the method comprising:

  • generating a plurality of waveforms corresponding to a plurality of frequency subbands for a predetermined frequency band, the predetermined frequency band being divided into a plurality of groups of subbands, the plurality of groups of subbands being divided into the plurality of frequency subbands;

    receiving a data signal;

    processing information associated with the received data signal;

    modulating the plurality of waveforms based on at least information associated with the received data signal;

    transmitting the modulated plurality of waveforms;

    wherein;

    any two of the plurality of waveforms are substantially orthogonal to each other;

    each of the plurality of waveforms corresponds to a waveform frequency spectrum associated with a spectral amplitude as a function of a frequency;

    the spectral amplitude for the frequency spectrum equals substantially zero outside a frequency subband selected from the plurality of frequency subbands, and equals substantially a constant number within the frequency subband.
