Abstract A novel system model using a non-binary Turbo concatenated codes is proposed based on analysis about the decoding algorithm of the non-binary Turbo codes in this paper. A shorted RS code(204,188)as outer code and a non-binary Turbo code as a inner code is separated in the system , Symbol-by-Symbol Log-MAP and SOVA algorithm is used in decoding the non-binary Turbo code .The conclusion by simulating is that proposed system has the features of low bit error ratio, low latency and high spectral, etc, compared to the other concatenated codes systems.
