Limited-trial chase-like bounded-distance decoding

The chase decoding algorithms are reliability-based algorithms achieving bounded-distance (BD) decoding for any binary linear code of Hamming distance d. The least complex version of the original chase algorithms ("Chase-3") uses O(d) trials of a conventional binary decoder. In this paper, we propose a class of Chase-like BD decoding algorithms of lower complexity than the original Chase-3 algorithm. In particular, the least complex member of this class requires only O(d²3/) trials.
