1. A method for communication in a time division multiplex system wherein access to a shared physical channel is assigned on a demand basis by allocating timeslots to provide multiple connections between transmitters and receivers, each given connection of the multiple connections having a given transmitter and receiver, the method comprising:

  • at a given transmitter, allocating at least one time slot to carry packet data;

    dividing the packet data into at least one frame;

    encoding each of the at least one frames with a forward error correction code;

    further cover sequence encoding each of the at least one frames with a cover sequence unique to the given connection between the transmitter and the given receiver;

    combining cover sequence encoded frames from the given transmitter with at least one cover sequence encoded frame from another transmitter; and

    at the given receiver, performing a cover sequence decoding process by combining a received signal with a cover sequence unique to the given receiver of the given connection, to provide a candidate frame; and

    decoding the candidate frame using a forward error correction decoding process, the cover sequence encoding operable to be decoded only by the cover sequence unique to the given receiver corresponding to the given connection.
