摘要
在高速无线数字通信系统中,正交频分复用(OFDM)技术因为它的频谱利用率高,成本低,并可以提供高速的传输速率,同时还很容易和多种多址技术相结合,所以正倍受瞩目。MC-CDMA和OFDMA就是两种常用的OFDM的多址接入技术,本文着重分析了两种方式在WLAN中的特点并进行了比较。
Orthogonal Frequency Division Multiplexing （OFDM） is an attractive technique for achieving high- bit- rote wireless data transmission. It has many advantages such as high spectrum utilizing rate and low cost, and can provide high transmission rote etc. It is also easy to combine with many multi- address technologies, among those are MC - CDMA and OFDMA. Their application in WLAN is discussed in this paper.
