| Abstract: | A novel and adaptive time-frequency （ATF） exciser for suppressing the interference in Direct Sequence Spread Spectrum （DSSS） communication systems is studied in this paper. The paper presents a performance evaluation of this excision technology via the theoretical calculation and computer simulation tools. It is found that the analytical performance tools match up with the computer simulation results. It is also shown that the proposed adaptive time-frequency exciser consistently outperforms the existing interference excision technology in the literature. |
