A method based on phase correction is proposed to enhance the performance of suppressing narrow-band interference of base-band direct sequence spread spectrum (DSSS) receiver. The received base-band DSSS signal is transformed by FFT, and the derived phase spectrum is compared with PN code’s and negative PN code’s phase spectrum. According to the comparing results, the phase spectrum of received signal is replaced by that of PN code or negative PN code with magnitude spectrum unchanged. After phase correction the received signal is transformed by IFFT to finish correlation. Two methods used for phase spectrum comparison are Sum-Absolute Difference (SAD) method and serial model distance method. The simulation results show that the performance of this phase-correction receiver is slightly worse than that of correlation receiver in AWGN channel, but better in condition of the existence of strong narrow-band interference, and the performance of SAD is better than that of serial model distance.
