摘要
对于有限域Fq上周期为N的多维序列,p为Fq的特征,当N与p互素时,定义了多维序列的扩域k错Fq线性复杂度,并用广义离散傅里叶变换的方法给出了多维序列扩域k错Fq线性复杂度的近似算法。
For the multisequences of period N over the finite filed Fq with characteristic p,gcd(N,p)=1,the notion of the extension field k-error Fq-linear complexity was defined and an approximation algorithm for computing the k-error Fq-linear complexity of the multisequences was given using the generalized discrete Fourier transform.
