Then based on the analysis of the constructions of wh, go and ls sequences, the corresponding correlation properties are derived and methods of selecting subsets with good periodic mean - square cross - correlation property or aperiodic mean - square correlation property from the wh set and go sequence set whose go zone z = l are investigated. furthermore, the methods of truncating the go sequences to obtain the quasi - orthogonal ( qo ) set whose family size m is larger than the length l and the quasi - generalized - orthogonal ( qgo ) set whose size m is larger than li2z are discussed, together with the numerical results of the correlation properties
基於這些結果,探討了如何從wh序列集和廣義正交區z = 1的go序列集中,分別按照周期互相關均方特性最優和非周期相關均方特性最優的準則選擇性能較好的序列子集;同時討論了將廣義正交序列截短來獲得準正交( qo )序列集和廣義準正交序列集( gqo )的方法,並給出了這一類序列相關特性的數值計算結果。 -
In this paper, the fuzzy uniform ring, fuzzy uniform subring, fuzzy uniform residue class ring, and direct product of fuzzy uniform rings are defined ; the three necessary and sufficient conditions to describe fuzzy uniform ring by the fuzzy topological ring of type ( qu ), by fuzzy uniform space and by a family of fuzzy subsets of a ring are obtained
摘要本文定義了模糊一致環概念,研究了它與模糊拓撲環的關系及它與模糊一致空間的關系;給出了藉助于環的模糊子集族對模糊一致環的刻畫,還引入了模糊一致子環,模糊一致剩餘類環與模糊一致環的直積;並討論了它們的分離性。
