Abstract:
This paper deals with a comparison of decoding algorithms for concatenated turbo codes. For this purpose we have implemented an algorithm of the concatenated convolutional turbo code in Matlab program. The algorithms used for decoding of turbo codes were Log-MAP and SOVA. To perform measurements we have simulated different communications conditions in the implemented model. We have evaluated the impact of the Signal/Noise ratio and the frame length on bit error rate (BER) for different decoders and finally compared the analysed decoding methods with theoretical limits.
