Application Study of the OFDM in the New Broadband Wireless LAN

The wireless LAN is of a high speed wireless data transmission system,for which it is very critical to choose the modulation technique.OFDM is a high speed modulation technique under wireless conditions,suitable to transmit high speed data in wireless mobile channel of multipath and Doppler frequency shift.It can waken the multipath effect availably,eliminate symbol interference and fight against frequency select fading.Moreover,the channel utilization rate is high.This article analyzes the OFDM applications in the wireless interface system of the new broadband wireless LAN.
