摘要(中) 衛星通訊系統因其所具有之獨特優勢,自出現以來便得到了迅速的發展,已成為未來通信系統不可缺少的重要組成部分,隨著無線通訊的蓬勃發展,通訊頻寬之需求也就與日俱增,促成寬頻衛星成為世界各國積極發展的目標,並著手研發高頻段之寬頻衛星,期能建構廣域、寬頻、無死角之無線通信體系,使得多媒體訊息的觸角能無遠弗屆地延伸。
由於展頻技術對頻帶的需求量大,因此具備較大頻寬的寬頻衛星無疑成為展頻技術最好的發揮之地。本論文基於寬頻衛星所具有之獨特性與重要性,依據寬頻衛星大頻寬之特性及展頻技術的運用,闡述寬頻衛星通訊系統在不同的展頻技術之相關設計下進行鏈路分析及系統規劃;另針對一具有各型不同天線大小終端站台之FDMA及DS-SSMA網路系統混合型(Hybrid)衛星通訊系統,並以功率「平衡」設計方法進行評估設計,以達到不致造成任何不想要之交互調變效應,期能在未來寬頻衛星通訊系統之規劃、設計與運用有所助益。
摘要(英) Satellite communication system has developed rapidly for its unique adavantages since it appeared and has become an essential part of telecommunication in the future. It’s for that the demand of communication bandwidth grows day by day with vigorous development of wireless communication to facilitate the broadband satellite to become the goal which countries all over the world positively want to develop. The technology of spread spectrum needs more bandwidth; therefore, it is the best way to accomplish the big bandwidth satellite communication. So that they all set about researching and developing the broadband satellite of high band, and hope that it can build and construct wide area, wide-band, and all visible wireless communication system to make that the coverage of the multimedia information can be extended borderlessly.
Because the technology of spread spectrume is limited to lack of frequency bandwidth, the “Big” bandwidth is the characteristic of the broadband satellite communication system that spread spectrum technology can use well. Therefore, spread spectrum technology plays an important role in the development of broadband satellite.The thesis based on the uniqueness and importance of broadband satellite, with the feature of broad bandwidth and spread spectrum technology would discuss the link-analysis and system scheme, and then Scheme of balanced power to evaluate the design of the the hybrid satellite communication systems combined with a conventional frequency-division multiple access (FDMA) system and a direct-sequence spread spectrum multiple access (DS-SSMA) system for the case of different types of ground based terminals to achieve that any unwanted intermoduation effect. We wish it useful to improve system scheme, design and application on the future broadband satellite communication.
