N2 - First, this paper analyzes the performance of the linear frequency modulation (LFM) interference in PN spread-spectrum communication systems. Second, in the light of suppressing the side-lobe of periodic LFM in fractional Fourier transform (FRFT) domain, a method combined transform-domain and time-domain is proposed, this method improves the processing gain and makes the distribution of the signal suppressed approximately Gaussian which is helpful for code acquisition. Finally, the simulation results show the method is valid.
