1. A destination station, comprising:

  • a receive buffer that accumulates information blocks until a condition is satisfied,wherein a sequence number identifies an outer code block to which each information block belongs, and a position of each information block within that outer code block;

    a reordering unit that utilizes the sequence number in each information block to reorder any information blocks that are received out of order; and

    a duplicate detection unit that utilizes the sequence number in each information block to detect duplicate information blocks, once the information blocks have been reordered, and eliminates any duplicate information blocks, andwhen the condition is satisfied for a given outer code block, the duplicate detection unit replaces any information blocks that do not pass a cyclic redundancy test by erasures, and generates a request to begin outer decoding.
