On Cyclic <formula formulatype="inline"><tex Notation="TeX">$q$</tex> </formula>-ary Images in Concatenated Form


This paper shows that q-ary images of some cyclic codes can be put into concatenated form in the sense of Jensen (1985). This description utilizes an isomorphism between the GF(q)-algebras GF(q) [z] / (z<sup>nm</sup> - 1) and GF (q )[x, y] / (x<sup>n</sup> - 1, y<sup>m</sup> - x). We also describe an element of the constacyclic outer code, which is of great… (More)
