dc.description.abstract近年來,數位通訊常被運用在更有效率和彈性的傳輸資料服務,一般而言,這些服務和它們所需求的網路轉移必須在高速的狀態下傳送,更多叢集式封包結構在實體層上被傳送,故實體層需要多路存取和調變及編碼的技術,以便能更有效率的傳送這些種類的資料, 特別是當頻寬和功率的資源有限時,這種技術更是重要。 乘積碼是是一種有效率的通道編碼方式,它的編碼結構簡單,且可與調變結合實現,有不錯的頻寬使用效率,現今IEEE 802.16 即採用疊代的乘積碼為標準,此外在衛星通訊、無線網際網路、 微波系統、行動通訊系統的應用上,乘積碼也伴演重要角色,本篇所要探討的,便是乘積碼的研究,及一些新的編碼方式,來改善它的效能。zh_TW
dc.description.abstractDigital communications links are used for the efficient and flexible transmission of a wide range of data services. In general, as these services and their supporting networks migrate towards higher rate, more bursty packet oriented structures, it is important that the physical layer have both access techniques and modulation / coding techniques to efficiently convey this type of data. This is especially important in the many applications in which both bandwidth and power are limited resources. Product code is one kind of efficient channel coding techniques. It has an simple coding structure, and it is easy to combine it with modulation. It is also easy to increase spectrum efficiency. For it''s application, IEEE 802.16 takes the Iteration Product Codes for it''s standard. Beside it, In Satellite Communication, Wireless Network, Microwave system, and Mobile Communication System, Product codes become an important role of them. In this paper, we would study on product code, and then, we may find a new coding technique for it, to improve it''s performance.en_US
