On base of the new definition of generalized duality multi-sequences over field FP , this paper presented the relation between the minimum polynomials of periodic multi-sequences and its generalized duality multi-sequences. Besides,it gave the properties about joint linear complexity of them. The results can be used to analyze the joint linear complexity of periodic multi-sequences of stream ciphers.%在提出P元周期多序列广义对偶多序列定义的基础上,讨论了P元周期多序列及其广义对偶多序列极小多项式之间的关系,研究了它们联合线性复杂度的性质.这些结果对研究流密码密钥流序列的联合线性复杂度有一定的应用价值.
