摘要 对多载频正交频分多址(MC-OFDMA)相关理论进行分析,并借助仿真方法研究MC-OFDMA传输的频谱效率。从理论方面可以导出,只要在MC-OFDMA传输的任何邻近的两个载频之间的频率间隔是整数倍的子载波间隔,则MC-OFDMA的传输就能够被正交化,并由此得出几种实现正交化MC-OFDMA的传输方法。仿真结果显示,正交化MC-OFDMA的传输在频谱效率方面优于非正交化MC-OFDMA的传输。 How to orthogonalize the multi-carrier frequency orthogonal frequency division multiple access （MC-OFDMA） transmission is herein discussed. The theoretical analysis reveals that MCOFDMA transmission shall be orthogonalized, only if the carrier frequency space between any two center carrier frequencies in the MC-OFDMA transmission is an integer multiple of the subcarrier spaces. Furthermore, the simulation results also demonstrate the advantages of the MC-OFDMA orthogonalized transmission over the non-othogonalized MC-OFDMA transmission in spectrum efficiency. Finally, several approaches are given how to orthogonalize the MC-OFDMA transmission.
