GENERALIZED HAMMING WEIGHTS FOR Goppa CODES AND BCH CODES
-
摘要: 本文研究了Goppa码、BCH码的广义Hamming重量,给出了Goppa码的广义Hamming重量的一个下界以及求该下界的一个算法;对于本原、狭义BCH码,给出了后面一些广义Hamming重量的确切值。Abstract: In this paper, generalized Hamming weights for Goppa codes and BCH codes are studied. Lower bounds of generalized Hamming weights for Goppa codes are obtained and an algorithm to find the lower bounds is given. Moreover, the last few generalized Hamming weights for narrow and primitive BCH codes are determined.
