燕山大学工学硕士学位论文Abstract 燕山大学工学硕士学位论文 Abstract As the fast development ofthe technology ofelectron,communication and computer,the function and the st删ure of aU kinds of electronic system is getting more and more complex．A much highly requirement for each capability and index of the system call for a higher requirement to the signals which are using．Therefore，people continue to research the new and the best signals to fix for the development of project．“Sequence pairs’’is a best signal that has been developed in these years，which extend the exist space for the best signal，and offset the limitation ofthe lack ofsome kinds ofbest signals．This paper is on the basis ofsequence pairs，combins generalized quasiorthogonality spread spectrum code and complementary sequence theory which applied in QS-CDMA system,defines two kinds of new the perfect discrete signals．The main work is just舔following： (1)The baSic concepts of sequence pairs and array pairs，the classes and correlation properties of them are introduced．Then introduces the app妣m ofthe sequence pairs． (2)The paper presents the definition of the generalized quasiorthogonality sequence pairs，the Fourier spectrum characters file studied．Then extends to the definition of the generalized quasiorthogonality sequence pair set(GQOPS)，we also give some examples of it．The paper discusses the transform properties of the correlation function about GQOPS．At last，we give the construction methods ofGQOPS． (3)Based on the binary complementary sequence，the paper defines the concepts of the complementary binary array pairs(CBAP)．Then presents the transform properties and the necessary condition ofthe special signal．At last，the Fourier spectrum characters are studied． Ⅱ Abstract(4)Based Abstract (4)Based on the basic construction methods of binary complementary sequence，the new type of CBAP constructes with composite method，and introduces the method ofhow to construct 2n,2(m+n)，m+n dimention CBAP by u∞ofn dimention CBAP． Keywords Spread spe
