%X In direct sequence spread spectrum narrow-band interference suppression is one of the difficult tasks in signal processing. This paper proposes a new narrow-band interference suppression algorithm called side correlation replacement algorithm based on side band correlation of signal. The signal carrier and center frequency of narrow interference are fixed on by calculating the side correlation function. Then narrow-band interference is eliminated when it is replaced by side correlation value. This algorithm is good for all modulation whose spectrum is symmetry. Computer simulation results demonstrate that the algorithm is more effective than transform domain interference returns zero.
