Abstract:The jamming effect of traditional blocking jammer on Wideband Code Division Multiple Access(WCDMA) by using spread spectrum technology is not good, and the implementation of WCDMA deceptive jammer is complex. An intelligent jamming system is designed based on the PicoZed SOM. Experiments show that when transmitted power is set at 23 dBm, this system can effectively block a range of ten meters WCDMA communication signal. The whole design is divided into four steps: firstly, a kind of jamming signal with the cell synchronization characteristics of WCDMA is designed based on WCDMA cell search process; secondly, MATLAB is adopted to verify the effectiveness of the method; thirdly, WCDMA jamming module and WCDMA DUC(Digital Up Converter) module are designed to generate the jamming signal on FPGA; lastly, the system is implemented based on the PicoZed SOM reference project provided by ADI to transmit WCDMA jamming signal to the air.
