| Abstract: | An algorithm for the suppression of narrowband interference in the direct sequence spread-spectrum (DSSS) systems is presented. It is based on a combination of frequency shifts with the undecimated wavelet packet transform. The simulation results show that it possesses very robust and nearly optimal performance. |
