The true dimension of certain binary Goppa codes
Marcel van der Vlugt · IEEE Transactions on Information Theory · 1990
By applying a result from algebraic geometry due to E. Bombieri (Amer. J. Math., vol.88, p.71-105, 1966), the true dimension of certain binary Goppa codes is calculated. The results lead in many cases to an improvement of the usual lower bound for the dimension.>
