For interference of Gaussian white noise and narrowband in wireless channel, overlap conversion FFT frequency domain notch filter algorithms can be adopted to reduce or eliminate relevant interference. Simulation analysis can be conducted in upon it in spread spectrum commu- nication system. Results show that the technology can greatly reduced the interference spectrum leak and the signal damage and it improves the accuracy and reliability of information transmission.
