  • We develop a cooperative decode-and-
    forward strategy of distributed Source-Relay network cod-
    ing for a three-node relay model, in which Relay and
    Source both send their own messages to Destination.
    First, we present a cooperative communication protocol to
    achieve decode-and-forward capacity by leveraging trans-
    mit rates between Source and Relay and designing dis-
    tributed Source-Relay network coding accordingly. After-
    wards, multi-dimension Low-density parity-check (LDPC)
    code is constructed as a layered structure, where Source
    LDPC, Relay LDPC, and network LDPC code are organi-
    cally integrated to realize a distributed design. Our design
    randomly embeds network-coded message into the layered
    structure as e®ective extra checks o®ering side informa-
    tion for both Source and Relay. Based on derivation of the
    algebraic relationship between constituent codes, a good
    multi-dimension LDPC code pro¯le is generated. Mean-
    while, network coding complexity maintains linear to the
    block length. The coding scheme is demonstrated to ap-
    proach decode-and-forward capacity and still provides ef-
    fective spatial diversity.
