dc.description.abstract在最新提出的光纖多樣性分碼多工系統,為以達到更好的傳送品質,每一個使用者的每個訊號都傳送多次相同的拷貝,且每個碼在傳送前使用不同的平移,以達到每個拷貝之間的獨立性。但是由於在短碼長且位元同步的情況下,難以僅使用不同位移而達到獨立性,故在這篇論文,我們將結合位元非同步和拷貝之間的獨立性這種更接近現實生活中的情況去分析光纖多樣性分碼多工系統並且推導出一個廣義的公式,更精準的模型。最後,我們將介紹不同的位移顆粒度,用以改善傳送品質與拷貝之間的相關系。zh_TW
dc.description.abstractIn our recently proposed diversity O-CDMA scheme, every simultaneous user transmitted multiple copies of an optical code per data bit of one in order to achieve good code performance. To maintain performance, our analysis showed that copy independency wasessential, which was achieved by time-shifting these copies to different chip (or time-slot) positions per bit duration. However, complete copy independency is hard to achieve under the conventional chip-synchronous assumption, especially in short code length. In this paper, we combine the realistic effects of chip asynchronism and copy dependency in the analysis of such diversity O-CDMA systems and formulate a new, generalized, and more accurate performance model. Finally, the improvement in copy independency and code performance due to the introduction of finer granularity in time-shfits among the diversity copies are studied.en_US
