p, m pozitif tamsayılar ve p ? 1 olmak üzere n = pm uzunluğundaki devirli kodlar yarıdevirli formuna dönüştürülebilir. Bu makalede iyi bilinen devirli kodlar kullanılarak GF(3) ve GF(7) üzerinde yarı-devirli kodların bazı parametreleri elde edildi.

SOME QUASI-CYCLIC CODES OVER GF(3) AND GF(7)

https://izlik.org/JA79DC32PN

Öz

Any cyclic code with n=pm length can be put into quasi-cyclic form ,where p ? 1, p,m + ? Z . In this paper, some parameters of the Quasi-Cyclic codes over GF(3) and GF(7) are obtained by using the best known cyclic codes.
