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。 -
Only a few have studyed family of problems. we extend the work in [ 26 ] - [ 27 ]. first, under the classical assumption that ( t ) ( t ), we consider the periodic boundary value problem, when / is independent of x ( t ). second, under the case that ( t ) ( t ), we consider the periodic boundary value problem and describe a constructive method which yields two monotone sequences that converge uniformly to extremal solutions to periodic boundary value problems, when / depends on x ( t )
氣t ）這一項的邊值間題更是如此，基於此，我們把微分方程方面的結果推廣到時間模上.首先考慮在下解小於上解的情況下， f不含。 （ t ）這一項的周期邊值問題，而後在下解大於上解的情況下，考慮了含有、 （ t ）這一項的周期邊值問題，描述了一種構造性方法，構造了兩個單調序列其一致收斂到二階周期邊值問題的極值解
