1. A method of utilizing a wireless communication spectrum, comprising:

  • receiving one or more wireless signals associated with a frequency and time map within the wireless communication spectrum;

    determining signal strength for the received wireless signals using wavelet analysis;

    comparing the determined signal strength for the received wireless signals to one or more threshold values;

    identifying as available, at least one cell within the frequency and time map based upon the comparison to the one or more thresholds;

    determining a scaling parameter and a shift parameter which identify the at least one cell, with the scaling parameter identifying time and frequency values of the at least one cell and the shift parameter identifying an energy concentration center in time for a wavelet wave form in the at least one cell;

    allocating the at least one cell for wireless transmission;

    generating a wavelet carrier signal based on the scaling parameter and the shift parameter; and

    wirelessly transmitting the wavelet carrier signal within the allocated at least one cell.
