| Abstract: | This paper puts forwards a stable IIR adaptive filter, along with the nonlinear gradient algorithm concerning its coefficient iteration. Simulation results demonstrate that under high JSR circumstance, the proposed IIR filter can efficiently suppress not only the CW interference but also the partial band NBI. |

| Keywords: | spread spectrum communications narrow band interference adaptive IIR filter nonlinear gradient algorithm |
