偽隨機序列和陣列的分層高速生成
HIGH SPEED HIERARCHICAL STRUCTURES FOR GENERATING PSEUDO-RANDOM SEQUENCES AND ARRAYS
-
摘要: 本文提出了一種新型的高速生成偽隨機序列和偽隨機陣列的分層結(jié)構(gòu)。該結(jié)構(gòu)的原理是基于一種新的概念多次插排,它是一般的序列插排(采樣)的推廣。該結(jié)構(gòu)的核心是一個低速的線性反饋移位寄存器和一些分層排列的高速時分多路器。這種新的結(jié)構(gòu)比作者以前提出的各種生成結(jié)構(gòu)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. -
