摘要
本文将二元非对称纠错码的构造推广到了q元的情形,给出了相应的下界及译码算法,并证明了一些早前已知的二元非对称纠错码的下界均可由该推广构造得到.
In this paper, we generalize some lower bounds, constructions and corre- sponding decoding algorithm from binary asymmetric error-correcting codes to the case q-ary. We show that some previously known bounds for binaxy asymmetric error-correcting codes can also be obtained for the generalization.
