碩士 === 中華大學 === 電機工程學系(所) === 94 === Since the WLAN was invented, information that transmitted through WLAN gradually increase and standards for high-speed WLAN are weeded through the old to bring forth the new continuously. Form the early IEEE Std 802.11-1997, IEEE Std 802.11b-1999 and IEEE Std 802.11a-1999 to the hottest WLAN standard, IEEE Std 802.11g™-2003, the speed of WLAN is up to 54 Mbit/s. Standards referred above will be introduced and implemented on software platform one by one. First, specification for each system would be introduced. Then, baseband transceivers, implemented with SIMULINK® and verified by the curve of BER (Bit Error Rate), would be performed. Next, performance of systems versus fading channel would be analyzed using transceivers constructed early. Finally, simulation of adaptive modulation controlling for IEEE Std 802.11a-1999 system would be performed under a principle estimated by the curve of system performance acquired early.
