| Abstract: | The characteristics of the narrow-band interference signal in the DSSS are firstly analyzed.Based on the shortcoming of LMS algorithm,the modified LMS Newton algorithm is used to deal with narrow-band interference.Compared with LMS algorithm,the stability and anti-jam performance of the modified LMS Newton algorithm are improved greatly.The interference rejection performance would be better if the appropriate control parameters were selected.Computer simulations show its effectiveness. |
