Let p be an odd prime, and m and k be two positive integers with m≥ 3. Let h±1 (x) and h±t (x) be the minimal polynomials of±α− 1 and±α− t over F p, respectively, where α is a primitive element of F p m. Let C 1,− 1,±t, C±1, t,− t and C 1,− 1, t,− t be the cyclic codes over F p of length p m− 1 with parity-check polynomials h 1 (x) h− 1 (x) h±t (x), h±1 (x) h t (x) h− t (x) and h 1 (x) h− 1 (x) h t (x) h− t (x), respectively. This paper determines the weight distributions of the cyclic codes C 1,− 1,±t, C±1, t,− t and C 1,− 1, t,− t for the parameter t satisfying some congruence equations.
