Abstract :
Based on analyzing the spectrum of narrowband interference, a method of suppressing narrow interference, which makes use of cyclostationary character of interference, is proposed in DSSS system in this thesis. The results of simulation indicate that this technique can suppress narrowband interference better than the estimator/subtracter filter in the time domain.
