| Abstract: | With the rapid development of WLAN in the recent years, IEEE802.11b has been an important approach to wireless data communication. But the 11Mbit/s data rate can't fit the multimedia service well. So attention is paid to IEEE802.11a based on OFDM by a lot of people. In this paper, IEEE802.11a is introduced at first. Then its principle and key technology are analyzed and the high rate WLAN system is disigned, at last the simulation and analysis of its performance is conducted. |
