摘要: 
With the popularity of mobile communications, the demand for data services has increased substantially, which facilitates the development of mobile communications and wireless network rapidly. Consumers' need and desire for Internet services anytime and anywhere gives rise to the massive transmission of multimedia data, triggering a new demand for wireless application in the mobile communications market. To fulfill this great demand, one of approaches is Frequency Hopping Code Division Multiple Access (FH-CDMA) technique because it can accommodate more users on the Internet and speed up the data transmission. In this thesis, we analyze the performance of Extended Reed Solomon Codes (E-RS codes) in the two-level FH-CDMA system by running a computer simulation, during which we also compare E-RS codes performance with RS codes when they are used as modulation codes. Finally we found that E-RS codes deliver sightly better performance than RS codes in the two-level FH-CDMA system.

由於現代行動通訊普及化,及網路的發展對數據服務的需求大為增加,消費者依賴各類型之智慧手機,因此造成大量多媒體資訊檔案的傳輸需求,挑戰更進一步行動市場無線應用領域的發展。而為了容納更多的使用者及資料傳輸速度,跳頻分碼多工技術提供了更多的用戶數、更快的資料傳輸速度。本篇論文中,我們使用延伸里德所羅門碼在二階層跳頻分碼多工系統上作電腦模擬效能。在此跳頻分碼多工系統中,延伸里德索羅門被選為調變碼,並與選用里德所羅門為調變碼分碼多工系統來做比較,我們發現延伸里德所羅門比里德所羅門系統在效能上有些微的改善。
