  • 摘要: 為了抑制或者消除準(zhǔn)同步碼分多址(QS-CDMA)通信系統(tǒng)的多址干擾(MAI)、多徑干擾(MI)以及鄰小區(qū)干擾，該文提出一類非對(duì)稱零相關(guān)區(qū)(A-ZCZ)序列偶集的構(gòu)造方法?；诮o定的最佳自相關(guān)序列偶，運(yùn)用交織操作，成功設(shè)計(jì)一類非對(duì)稱零相關(guān)區(qū)序列偶集。新集合的每個(gè)子集均是零相關(guān)區(qū)序列偶集，且不同子集的序列偶間的互相關(guān)函數(shù)(CCF)具有更大的零互相關(guān)區(qū)(ZCCZ)。同時(shí)，該文提出的構(gòu)造方法可以根據(jù)系統(tǒng)要求靈活地選擇子集的零相關(guān)區(qū)寬度。
    Abstract: In order to eliminate the Multiple Access Interference (MAI) and Multipath Interference (MI), and avoid inter-cell interference from adjacent cells in Quasi-Synchronous Code Division Multiple Access (QS-CDMA) system, one class of asymmetric sequences pairs with Zero-Correlation Zone (ZCZ) are proposed. Based on the interleaved technique, a new Asymmetric-ZCZ (A-ZCZ) sequence pair set can be generated from a given perfect auto-correlation sequence pair. The presented A-ZCZ sequence pairs contains of multiple subsets which are the traditional ZCZ sequence pairs. The Cross-Correlation Function (CCF) between any two sequence pairs of different subsets has a wider Zero-Cross-Correlation Zone (ZCCZ). As a benefit, the ZCZ length of A-ZCZ sequence pair set can be flexibly chosen according to the requirement of the system.
