| Abstract: | An anti-jamming algorithm for narrow-band interference in direct sequence spread spectrum systems ,which is based on the adaptive IIR notch filtering is introduced.An adaptive line enhancer(ALE) is used to estimate the instantaneous frequency and power of interference, the depth of the notch is adjusted by using the adaptive lattice IIR notch filter , so as to improve the SNR of output signal. |

| Keywords: | Narrow-band interference Adaptive IIR notch filter Adaptive line enhancer Anti-jamming |
