【摘要】 本文研究由折合m序列构成的伪随机阵列(PRA)。这种PRA的每一列均为m序列的非完全采样。因此本文先研究m序列在非完全采样情形下,采样序列之间一般的相位关系,由此得出了一个公式,此式可以确定采样间隔相同而采样起点不同的采样序列之间的相位关系。再利用此式确定出PRA列与列间的相位关系。最后,根据这些关系,设计出了一种简单电路,可以按行产生PRA。更多还原

【Abstract】 In this paper, we study one kind of pseudo-random arrays (PRA) constructed by folding an m-sequencs. For this kind of PRAs, each column is an improper decimation of the m-sequence. At first, we study the genaral phase relation among the sample sequences in the case of improper decimation. As a result, we obtain a formula which gives the phase relation among the sample sequences with same sampling interval but different initial sampling points. Using the formula, we can determine the phase relation among the columns of the PRA. At last, we synthesize a simple circuit which can generate the PRA row by row.更多还原
