| 摘 要： | 1966年提出的级连码是一类纠错能力强的渐近好码,它将在空间通信中得到广泛应用。本文研究RS/Viterbi级连码,从理论上证明了它的性能满足Zyablov限;探讨了RS/Viterbi级连码的编译码方法,对RS码的连分式译码方法作了改进,使之更适于实用。

| Abstract: | Concatenated code proposed in 1966 is an asymptotic good code, which has powerful error-correcting ability. It will be applied in space communication widely. In this thesis, the RS/Viterbi concatenated code is studied. It is verified theoretically that the performances of RS/Viterbi concatenated code meet the Zyablov bound. Moreover, Its encoding and decoding methods are discussed, and for the sake of utility, the RS's continued fraction decoding method is modified. |
