| Abstract: | As is well known,turbo code has performance close to the Shannon-bound due to its iteration decoding.A scheme of coding and decoding for Turbo codes in deep-space communication is presented in this paper.Moreover,a software simulation and hardware implementation of the CCSDS turbo code with modified MAX-Log-Map decoding algorithm have been described.Simulation results show that the modified MAX-Log-Map decoding algorithm can be implemented in hardware easily.Furthermore,the performance of software simulation agrees with that of hardware implementation. |
