摘要: 本文提出了一种新型的高速生成伪随机序列和伪随机阵列的分层结构。该结构的原理是基于一种新的概念多次插排,它是一般的序列插排(采样)的推广。该结构的核心是一个低速的线性反馈移位寄存器和一些分层排列的高速时分多路器。这种新的结构比作者以前提出的各种生成结构的生成速度都要高得多。Abstract: This paper proposes new hierarchical structures for generating pseudo-random sequences and arrays. The principle of the structures is based on a new concept-multi-interleaving, the generalization of normal sequence decimation(sampling). The kernel of the structure is a lower speed linear feedback shift register together with several high speed time-division multiplexers arranged hierarchically These new structures have much higher speed compared with that of other schemes proposed before.
