Abstract: A new class of cyclic codes of length 2n over GF(q) is proposed, where q is a prime of the form 8m ± 3 and n > 3 is an integer. These codes are defined in terms of their generator polynomials. These codes have many properties analogous to those of duadic codes. Generator polynomials of some duadic codes of length pn over GF(q) are also discussed, where p is an odd prime, n is an integer and q = ρ or ρ² for some prime ρ.
Keywords: cyclic codes; generator polynomials; duadic codes; qr codes; prime power length.
