| Abstract: | The SNR loss bring by narrow-band interference excision in LEO satellite spectrum-spread communication system is intro-duced,then propose a new digital AGC(Auto Gain Control)to provide constant power level after interference excision.In the protec-tion of AGC,the SNR loss can be controlled in 1dB. |

| Keywords: | narrow-band interference excision digital AGC SNR loss |
