OFDMA是根据频分多路传输系统的思想，这是一种在一个频道上传输多个数据流的方法。

OFDMA is based on the idea of frequency-division multiplexing, which is a method to transmit multiple data streams over a channel.

LTE则利用频分多路传输系统把频道分成两个部分，所以，下载和上传的速度得以更好地平衡。

LTE splits the channel into two parts using frequency-division multiplexing, so the download and upload speeds are better balanced.
