When the complementary sequences can be constructed , it is called constructible complementary sequence 特征序列對研究互補序列的特性具有重要意義。
Thus the sequence of nucleic acids on one chain defines a unique , complementary sequence on the other chain 這樣在一條鏈上的核酸分子排列的順序確定了一個獨一無二的、互補的與另一條鏈相連接的次序。
The property of complementary sequence pairs is studied , and a new denotation figured by three sequences is introduced in this paper 互補序列偶是由4個序列組成的滿足一定互補性的序列組,它是互補序列理論的相關(guān)概念的延伸。
As a new type of perfect signal , the complementary sequence pairs would possibly have good future application in communication engineering 目前發(fā)現(xiàn)的互補序列的核只有3種,所以其空間大小受到限制,因此引入了互補序列偶理論。
Complementary sequences are the most representative perfect signals that have good aperiodic correlation feature . the binary complementary sequences were introduced in 1949 具有良好非循環(huán)相關(guān)特性的最佳信號的序列中,互補序列最具有代表性。
This thesis researches on reducing the par of mc - cdma from two different points . on one side , this thesis studies behaviors of mc - cdma with golay complementary sequences as spreading sequences 一方面,本文利用格雷互補序列作為mc - cdma信號的擴頻碼,有效降低其峰值平均功率比。
We also deduced the maximum of correlative function of the odd length complementary sequence pairs . on the basis of the property that was found in this paper we have designed a searching arithmetic 互補序列偶的長度不受限制,任何長度的互補序列偶都存在,因此互補序列偶理論的研究具有重要意義。
Then we have searched out all of the unequal complementary sequence pairs with length up to 20 . we have got some suppositions from the searching results , though the correctness of it is waiting for prove 并由此設(shè)計了最佳二元互補序列偶的快速搜索算法,搜索出長20以內(nèi)的所有最佳二元互補序列偶的等價類。
Antisense nucleic acid technique is a method using single - stranded complementary sequences with specificity assigned by watson - crick base - pairing targeted specific messenger rna or dna to block expression of target gene 反義核酸技術(shù)是根據(jù)堿基互補原理,使用與目標(biāo)靶的遺傳物質(zhì)( mrna或dna )特定互補的核酸片段封閉基因表達的技術(shù)方法。
The equivalent relation between the families of bent complementary function pairs and the families of dyadic complementary sequence pairs is discussed , so are the families of hadmard complementary array pairs 首先,提出了bent互補函數(shù)偶族的概念。其次,深入地研究了它的性質(zhì),特別是與hadamard互補矩陣偶族、并元互補序列偶族的等價關(guān)系。
In applied mathematics, complementary sequences (CS) are pairs of sequences with the useful property that their out-of-phase aperiodic autocorrelation coefficients sum to zero. Binary complementary sequences were first introduced by Marcel J.
