Global positioning system (GPS) signal is weak and vulnerable. Using the frequency-domain notching filter cascaded with space domain filter can improve the anti-jamming ability of the GPS receiver. However, when the narrowband jamming falls in the wideband one, it is difficult to detect the narrowband jamming spurs correctly by fast Fourier (FFT) transform.(More)
CDMA communication system has a certain anti-interference performance, but when the interference is stronger, the performance and stability of system will descend obviously. In this paper, narrow-band interference suppression based on FFT transform is adopted to improving anti-interference performance of CDMA communication systems significantly. Probability(More)
