| 摘 要： | A multi-dimensional concatenation scheme for block codes is introduced.in which information symbols are interleaved and re-encoded for nmore than once.It provides a convenient platform to design high performance codes with flexible interleaver size,Coset based MAP soft-in/soft-out decoding algorithms are presented for the F24 code.Simulation results show that the propsed coding scheme can achieve high coding gain with flexible interleaver length and very low decoding complexity.

| Abstract: | A multi dimensional concatenation scheme for block codes is introduced, in which information symbols are interleaved and re encoded for more than once. It provides a convenient platform to design high performance codes with flexible interleaver size. Coset based MAP soft in/soft out decoding algorithms are presented for the F24 code. Simulation results show that the proposed coding scheme can achieve high coding gain with flexible interleaver length and very low decoding complexity. |
