Abstract

In this paper, the performance of a non-binary convolutional turbo codes is evaluated through computer simulations. Especially, The influence of the various frame sizes and code rate are discussed. Also, in this paper the symbol-by-symbol MAX-Log-MAP algorithm is derived for this coding scheme. We present simulation results for the performance of the non-binary convolutional turbo coded system with QPSK, 16QAM, and 64QAM over an AWGN and the ITU-R channel models.
