摘要

在频率选择性衰落环境下，使用单载波将编码数据从发送端传输到接收端，会导致信号失真，导致性能不佳。但是，如果使用一个以上载波传输相同的编码数据，则可以组合来自每个子载波的接收数据以实现改进的性能。这种类型的传输称为多载波(MC)码分多址(CDMA)方案。本文介绍了MC-CDMA方法的优点。

Application of multicarrier CDMA to mobile communication technology

In a frequency selective fading environment, use of a single carrier for the transmission of the encoded data from the transmitter to receiver, causes signal distortion resulting in poor performance. But if the same encoded data is transmitted using more than one carrier then the received data from each subcarrier can be combined to achieve improved performance. This type of transmission is called a multicarrier (MC) code-division multiple access (CDMA) scheme. The advantages of an MC-CDMA approach are presented by the authors in this paper.
