摘　　要：针对OFDM信号容易受到子载波间干扰（ICI）这一事实,提出一种全新的干扰方式——利用人为多普勒频移对OFDM信号进行干扰。在正常通信接收方采用一般ICI抵消的基础上,定量分析了这种全新干扰方式对正常通信接收方所造成的信噪比损失,为设计人为多普勒频移干扰提供了指导。Based on the fact that the OFDM signal is sensitive to the ICI, we proposed a novel interference method for jamming the OFDM signal which is called as the man-made doppler frequency offset interference. In this paper, we analysis not only the performance of the novel interference method but also the SNR loss caused by the interference. The results in this paper can guide the design of the man-made doppler frequency offset interference.
