Summary: | 碩士 === 國立臺北科技大學 === 光電工程系所 === 94 === 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.
