摘要：
On the basis of the theories of spread spectrum communication systems and narrowband interference suppression, this paper improves the narrow-band interference suppression in transform domain based on adaptive multi-threshold algorithm, applies the adaptive filtering algorithms in the narrow-band interference suppression. The arc tangent function improves convergence speed and suppression performance by introducing coefficient of variation which can be carried out in project was applied in the variable step-size LMS algorithm. The method for suppressing low-bandwidth interference in DSSS was proposed with simulation results.
