Abstract

The Linear frequency modulation (LFM) interference can seriously deteriorate the performance of the direct-sequence spread spectrum (DSSS) communication system. So people usually use time-frequency transform to suppress the LFM interference. In this paper, we use the fraction Fourier transform (FRFT) to suppress the LFM interference in the DSSS communication system. The simulation results show that the performance of the system is improved greatly after the LFM interference is suppressed with the FRFT.
