摘要：
This paper proposes a linear FM interference rejection method in direct sequence spectrum spread (DSSS) communication system based on signal synthesis using fractional Fourier transform. The detection and parameter estimation of the interference signal are implemented in fractional Fourier domain and the synthesized estimate of jamming signal is then subtracted from the received signal, the interference immunity of the system can thus be improved. Performance analysis and simulation results showed that, the proposed method works effectively in a wide dynamic range of SNR, and also, it is easy in computation and simple in implementation.
