1. A process for allocating carriers in a multicarrier system, the process comprising:

  • determining a location of a subscriber with respect to a base station;

    selecting carriers from a band of multi-carriers to allocate to the subscriber according to the location of the subscriber with respect to the base station;

    allocating selected carriers to the subscriber, and indicating to the subscriber whether or not to adjust transmit power to above its normal transmit power range based, at least in part, on the selected carriers allocated to the subscriber;

    wherein the closer the subscriber is to the base station the farther away the selected carriers are from the center of the band to reduce effects of inter modulation distortion (IMD) products and spectral re-growth caused by the subscriber on an adjacent channel.
