1. A communications system, comprising:

  • a mobile unit operable to transmit redundant content to a plurality of base transceiver stations, a copy of the content transmitted to each base transceiver station being encoded using a code that is related to the codes used to encode copies of the content transmitted to the other base transceiver stations;

    a plurality of base transceiver stations, each base transceiver station operable to;

    receive a copy of the coded content from the mobile unit;

    generate a packet including the coded content; and

    communicate the packet; and

    a decoder operable to;

    receive a plurality of packets each including a copy of the coded content, each packet generated at a different base transceiver station;

    decode the content in the packets by concatenating the related codes used to encode each copy of the content; and

    generate one or more redundant packets including the decoded content.
