摘要 正交频分复用OFDM(OrthogonalFrequencyDivisionMultiplexing)是一种高效的数据传输技术,具有良好的抗多径干扰的能力,但各子载波频率的偏移,会造成严重的载波间干扰。文中提出了一种基于差分调制消除OFDM系统子载波间干扰的方法,并与标准的mPSK调制OFDM系统进行了对比。仿真结果表明:差分调制能够有效消除频率偏移造成的OFDM系统子载波间的干扰。并且计算简单,不牺牲系统的带宽利用效率,具有很好的实用性。 OFDM is an effective technique in data transmission. It has a better capability against multi-path interference, but the frequency offset of the sub-carriers may cause a severe inter-carrier interference. We first presented a scheme to reduce the inter-carrier interference between the sub-carriers of the OFDM system based on the differential modulation. Then we compared it with the OFDM system based on the standard mPSK modulation scheme. The simulation shows that the differential modulation scheme can reduce the inter-carrier interference effectively and needs little calculation time. It is practicable in that it doesn't cause a reduction in bandwidth efficiency.
