Abstract

Two construction techniques for variable-length error-correcting (VLEC) codes are given. The first uses fixed-length linear codes and anticodes to build new VLEC codes, whereas the second uses a heuristic algorithm to perform a computer search for good VLEC codes. VLEC codes may be used for combined source and channel coding. It is shown that over an additive white Gaussian noise channel the codes so constructed can perform better than standard cascaded source and channel codes with similar parameters.
