A subchip multipath search method for DSSS system based on Fractional Fourier Transform(FrFT) is proposed. Chirp signal is used as pilot signal, the multipath chirps are processed by FrFT at receiver, then the relative delays between multipath chirps can be calculated after detecting peak positions in FrFT domain according to the linear relationship between the relative delay in time domain and difference between peak positions of multipath chirps in FrFT domain. The search resolution is equal to reciprocal of the bandwidth of chirp signal, so the chirp signal with bandwidth larger than that of DSSS signal should be used to resolve subchip multipath. Simulation results show that the proposed method can calculate the relative delays of subchip multipath effectively.
