摘要: 
隨著不同行動無線應用需求之增加,無線通訊技術也蓬勃發展。而為了支援不同多媒體服務,系統必須要能支援更多的同時使用者及不同的資料傳輸速率。跳頻分碼多工技術可彈性的提供這些多媒體應用服務之需求。在此論文中,我們提出一個使用延伸里德所羅門碼之跳頻分碼多工系統並使用電腦模擬來分析此系統的效能。我們同時也提供使用多階層質數碼跳頻分碼多工系統來與所提出之系統做比較。我們發現所提出的延伸里德所羅門碼系統除了比多階層跳頻分碼系統在效能上有些微的改善,同時也可提供碼長度額外選擇之彈性。


關鍵詞:跳頻分碼多工系統、里德所羅門碼、多階質數碼、延伸里德所羅門碼。

Abstract
The technologies of the communication systems go flourishing as the demands of various wireless applications increase. To support different multimedia services, the systems need to accommodates more simultaneous users with different data rates. Frequency-hopping code-division multiple access (FH-CDMA) is one of promising technologies which can provide such flexibilities to these multimedia applications. In this thesis, an FH-CDMA system with extended Reed Solomon (RS) codes is proposed and analyzed with computer simulations. In the meantime, the simulations of an FH-CDMA system with multi-level prime codes (MPCs) are provided and compared with the propose system. We showed that the proposed system with extended RS codes has slightly better system performance than the system with MPCs and provide additional options on the selections of the code length.
