正交频分复用技术在高速无线局域网上的应用

Application of OFDM Technology in High-Speed WLAN

研究OFDM在高速无线局域网中的应用与实现。当高速的数据在陆地无线信道中传输时,会产生严重的码间干扰,除非传输符号的持续时间足够长,这就严重的限制了无线通信的速率。OFDM就是解决这个限制的方法之一。

Researches on the application and implement of OFDM in the high-speed WLAN. Inter symbol interference usually occurs when data are transmitted over a FSF channel unless the symbol duration is much larger than the channel impulse response duration. This imposes a severe limit on the symbol rate unless the receiver employs some technique to mitigate ISI. OFDM is one of the ways that can solve this restriction.
