1. A transmitter for a multi-carrier terminal, comprising:

  • a first transmission circuit for providing a first carrier for a first channel;

    at least a second transmission circuit for providing at least a second carrier for a second channel;

    a combiner connected to the transmission circuits for combining the first carrier and at least the second carrier into a multi-carrier signal;

    a power amplifier connected to the combiner for amplifying the multi-carrier signal; and

    a processor connected to a power detector and to the transmission circuits for apportioning power available for the amplified multi-carrier signal between the first and second carriers according to a carrier priority, wherein the carrier priority allocates to the first carrier a first carrier portion of the transmission power, and allocates to the second carrier a second carrier portion of the transmission power, the second carrier portion being based on the power available for the multi-carrier signal reduced by the first carrier portion.
