摘要

Let ^Fr be an extension of a finite field F_q with r=q^m. Let each ^gi be of order ⁿⁱ in _r^* and gcd(ⁿⁱ,^nj)=1 for 1≤i≠j≤u. We define a cyclic code over F_q byC(q,m, ⁿ¹,ⁿ²,.,^nu)={C(^a1, ^a2,.,^au):a₁,a₂,.,a _u⋯^Fr}, whereC(^a1,^a2,., ^au)=(Trr/_q(Σi=1u^aigi0),.,Trr/ _q(Σi=1u^aigin-1)) and n=ⁿ¹ ⁿ²⋯^nu. In this paper, we present a method to compute the weights of C(q,m,ⁿ¹,ⁿ²,.,^nu). Further, we determine the weight distributions of the cyclic codes C(q,m, ⁿ¹,ⁿ²) and C(q,m,ⁿ¹,ⁿ²,1).
