摘要
An optimised construction of variable-length error-correcting codes (VLEC) is proposed in this paper. Compared to the state-of-the-art, the three main improvements consist first in improving the codewords search algorithm complexity/efficiency trade-off, second in loosening the codewords deletion rule, and third in taking advantage of eventual previous searches. It is shown that the optimised algorithm can find good VLEC codes for alphabets up to 200 symbols, and outperforms existing algorithms.
