1. between two or more equipment, with minimum data rate, carry out a method for radio communication, described method comprises following action:

  • A) detect the energy level on one or more subchannels;

    AndB) energy level based on subchannel described in each is detected is subchannel selection modulation scheme and error correction coding scheme described in each;

    Described method also comprises;

    C) based on selected modulation scheme and selected error correction coding scheme, calculate overall transmission rate;

    AndD) if described minimum data rate surpasses described overall transmission rate, on a sub-channels, select the modulation scheme of higher-order.
