摘要 多载波CDMA(MC-CDMA)是将多载波调制OFDM与DS-CDMA结合起来的多址访问技术。如何从接收到的信号恢复出发送信号,涉及到频率分集接收和均衡。本文提出的能量受控均衡技术,在多用户的环境下能较好地恢复扩频码的正交性且避免信道深度衰落的影响,而且,实验表明该方法对于不同的信道状况均能很好适应。 Multi-carrier CDMA(MC-CDMA) is a multi-address access technique which concatenates OFDM and DS-CDMA. How to retrieve transmitted signals from received signals concerned with frequency diversity and equalization. Energy controlled equalization technique, proposed by the author, can well restore the orthogonality of spreading code and avoid effects of deep fading of channel in the case of multi-user environment. And experiments show that it is suitable to different channels.
