In this paper we prove that the class of Goppa codes whose Goppa polynomial is of the formwhereis a trace polynomial from a field extension of degreehas a better minimum distance than what the Goppa boundimplies. This result is a significant improvement compared to the minimum distance of Trace Goppa codes over quadratic field extensions (the case). We present two different techniques to improve the minimum distance bound. For generalpwe prove that the Goppa codeis equivalent to another Goppa codeC(M,h) where. Forwe use the fact that the values ofare fixed underq–powers to find several new parity check equations which increase the known distance bounds.
