Abstract |
|
Let q=3l+2 be a prime power.Maximal designed distances of imprimitive Hermitian dual containing q2-ary narrow-sense
(NS) BCH codes of length n = (q6−1)
3 and n = 3(q2 −1)(q2 +q+1) are determined. For each given n, non-narrow-sense (NNS) BCH
codes which achieve such maximal designed distances are presented, and a series of NS and NNS BCH codes are constructed and
their parameters are computed. Consequently, many families of q-ary quantum BCH codes are derived from these BCH codes. Some of
these quantum BCH codes constructed from NNS BCH codes have better parameters than those quantum BCH codes available in the
literature, and some others are new ones. |
