在本論文中,主要是建構能應用在目前無線通訊領域上的光纖-微波系統。我們提出了三種符合 IEEE 802.11a、IEEE 802.11b、PHS / VICS / ETC / SB 等無線通訊規範的光纖-微波傳輸系統如下: 在IEEE 802.11a的通訊協定標準下 (5GHz / 54Mbps) ,利用光纖-微波(Radio-on-MMF)去做傳輸,我們使用外部光注入技術和一個能對三階互調失真項做補償的技術,去抑制整個系統中射頻訊號間的互調失真項。 另外,在符合 IEEE 802.11b 通訊協定標準 (2.4GHz / 11Mbps) 的光纖-微波系統(Radio-on-DWDM) 裡,使用了低成本的自發輻射放大光源,並利用外部光注入半導體光放大器的技術,改善其誤碼率、三階互調失真載波比和誤差向量值等。 最後在符合個人行動電話 1.9GsHz / 10Mbps、車輛資訊與通訊系統 2.5 GHz / 12 Mbps、電子收費系統 5.8 GHz / 20 Mbps 和衛星廣播 12 GHz / 25 Mbps 的資料傳輸標準下,使用了大有效面積光纖去取代了傳統的單模光纖,並且在系統中另外也使用一些補償技術,使得在系統接收端的訊號品質提昇。
In this dissertation,we primarily employ “Radio-on-Fiber” transport systems applied present wireless communication.We propose three “Radio-on-Fiber” transport system that correspond the standard for “IEEE802.11a”,”IEEE802.11b” and “PHS/VICS/ETC/SB”,as follows: Employing “Radio on MMF” transport system in the IEEE 802.11a standard(5GHz/54Mbps),we utilize both laser injection locked and third-order intermodulation distortion (IMD3) suppression techniques to suppress intermodulation distortion coefficient between radio frequency(RF) signals. In another case,employing “Radio on DWDM” transport system in the IEEE802.11b standard(2.4GHz/11Mbps),we utilize a low cost amplified spontaneous emission(ASE) source and impove this system’s bit error rate(BER),three-order intermodulation distortion to carrier ratio(IMD3/C) and error vector magnitude(EVM) by using semiconductor optical amplifier injection locked technique. Finally,in the PHS demand with a data signal of 1.9GHz/10Mbps,VICS demand with a data signal of 2.5GHz/12Mbps, ETC demand with a data signal of 5.8 GHz/20Mbps and SB demand with a data signal of 12GHz/25Mbps,we utilize large effect area fiber(LEAF) to replace single mode fiber (SMF),and also employ some compensative technique to promote qualities of signal in the receiver.
