Remarks on codes from Hermitian curves (Corresp.)

Parameters and generator matrices are given for the codes obtained by applying Goppa's algebraic-geometric construction method to Hermitian curves in PG
(2,q)
, where
q = 2^{2s}
for some
s\in {\bf N}
. Automorphisms of these codes are also discussed, and some results on self-duality and weak self-duality are given.
