dc.description.abstract在本篇論文中,我們建構出一種新的“多階層”波長-時間二維光纖碼,稱之為延伸多階層質數碼。此新建構之二維光纖碼的最大相關性函數值為任意之正整數n,自相關性函數值為零,並且相較於以往所提出的多階層質數碼,擁有更多的碼總數量以及極具彈性的碼長,此外,碼數量亦為最佳化之設計。新的二維光纖碼可以分為n個階層,其中若位於階層l時,任意兩碼矩陣之間的相關性函數值最大則為l。藉由導入階層的概念,可針對不同的系統需求,與考量到系統效能和同時使用用戶數目的情況下,選擇合適的階層作分碼多工。zh_TW
dc.description.abstractIn this thesis, a new family of “multi-level” wavelength-time codes with expanded code cardinality, flexible code length, zero autocorrelation sidelobes, and the maximum cross-correlation function of any arbitrary positive integer n is constructed and analyzed. Besides having asymptotically optimal cardinality, the new codes can be partitioned into n levels, such that the cross-correlation function between any two code matrices in level l is at most l, where 1 l n. The performance of these multi-level codes in an optical code-division multiple-access system with hard-limiting detection is analyzed algebraically. Our results show that the unique partition property of these multi-level codes supports a trade-off between code cardinality and performance for meeting different system requirements, such as user capacity and throughput.en_US
