The Structure and Performance of High Rate Turbo-Codes

  • Publish Date: 25 Aug 2000
  • There are multi-dimension and punctured methods for constructing Turbo-codes. The interleave design and punctured matrixstructure in constructingTurbo-codeswith the punctured method are discussed. Through the analysis of the free distances and decoding of high rate Turbo-codes constructed by the above two methods, their bit error limits are obtained, fromwhich theTurbo-codes constructed bymulti-dimension method are found to have better performance than those by punctured method, but with more complex decoding and bigger time delay. Comparison shows that with better compromise in performance and implementation complexity, the punctured method is an ideal scheme to construct high rate Turbo-codes.
