Abstract: Decoding algorithms [1-3] are designed to recover information after its transmission over a noisy communication channel. Soft decision decoding algorithms are very powerful in concatenation schemes using two or more decoding levels. In this paper, we concatenated a symbol-by-symbol decoder [4] and a word-to-word decoder [5] with the aim of decoding linear block codes. We will use firstly the symbol-by-symbol decoding algorithm with less number of dual codewords then the word-to-word decoding algorithm, which exploits the output of the first decoder. We noticed that the proposed decoding ...
