This paper discusses analysis and synthsis of one kind of nonlinear sequences generators DKG which consist of a linear feedback shift register ( LFSR) with a primitive connective polynomial, a random select generator and a nonlinear feedforward function. 本文讨论一类非线性生成器的分析与综合。这类非线性生成器由三部份组成:nm级的带有本原联结多项式的线性移位寄存器,随机选择器;
