Negacyclic codes of length 2~mp~n over a finite field
Shen Ru · Scientia Sinica Mathematica · 2013
Let F_q be a finite field of odd order q. The polynomial generators of all negacyclic codes of length 2~mp~n over F_q are obtained, where p is an odd prime divisor of q-1 and m, n are positive integers; all self-dual negacyclic codes of length 2~mp~n over F_q are also precisely characterized.
