Simulation indicates that the par of mc - cdma can be upper bounded 6db by using golay complementary sequences and s - r sequences as spreading sequences , which is much superior to m sequences and hadamard sequences . on the other side of view , compared with the old basic selected mapping method , this thesis proposes some other selected mapping algorithms and compares the performances based analysis and simulation 仿真表明,采用格雷互补序列作为扩频码来降低峰平比,不论是效果还是实用性,都大大优于m序列和hadamard序列;另一方面,本文在基本选择映射算法基础上,提出了几种改进的选择映射算法。
Now there are 5 constructive methods have been found , through which all of the complementary sequences whose length is 2 ' 10s26 " can be constructed . it was proved in this paper that it can determine which equivalence class is constructible or not by the feature seque nce . based on the reseach and computer we have got all the equivalence complementary sequence class with length of not more than 40 , and found a new complementary sequences kernel with length of 20 经分析发现当序列长度n 4时,可以根据特征序列来判断互补序列等价类空间大小,这对实际应用中互补序列的选取具有一定意义;此外本文证明了互补序列等价类的唯一性,即不同的等价类不能包含相同的序列;对互补序列的各种构造方法进行分析,发现通过每种构造方法构造出的互补序列其特征序列均具有某种特性,通过论证得出可以通过特征序列来判断互补序列是否是可构造的以及可以由哪种构造方法构造,并通过特征序列证实了长度为20的互补序列的核的存在性。
Its and 5 . 8s rrna genes of 4 species in the cardamine were sequenced . sequences of all species are complete in the useful segments and the results of the two - way sequencing are complementary sequences , which indicates that the evolution of its repeating units of those species had synchronized with a high degree ) 4种植物的核糖体dna中的内转录间隔区( its )序列及5 . 85 : rna基因全序列,在有效的区段内,序列数据完整无缺,且正、反向测序结果完全互补,这表明所用材料的its重复单位同步进化程度很高。
On the basis of theory analysis and reasoning , cdma single user system models based upon binary complementary sequences and complete complementary sequences are successfully built by use of s - function . and respectively taken 8 - bit , 16 - bit binary complementary sequence and one subset of 4 - order complete complementary sequence as examples , the simulations of all the functions of the system are realized . the result proves that it is proper and feasible to use the modified complementary sequences to cancel multi - path interference 本论文在前面几章理论分析及论证的基础上,用matlabsimulink中的s - function成功构建了基于修正二元互补序列cdma单用户系统模型和基于修正完备互补序列cdma单用户系统模型,并且分别以8位长, 16位长二元互补序列以及4阶完备互补序列的一个子集为例,实现了对系统各项功能仿真,结果证明采用修正互补序列实现抗多径干扰的思路是正确的而且是可行的。
Now the research of it has made a great achievement , based on it we studied the feature of the binary complementary sequences . the feature sequences of complementary sequences are introduced in this paper . every complementary sequence has two kinds of feature sequences 目前互补序列的研究取得了丰富研究成果,在这些研究成果的基础上,进一步对互补序列的特性进行研究,并引入了互补序列的特征序列的概念,定义每个互补序列包含两种特征序列,分别记为1 -特征序列和2 -特征序列。
