Interference-avoiding Wireless Transmission Technology Based on Transform-domain Design
Authors:KANG Gui- hua  CHEN Wen- fang
Abstract:The basic principle of interference-avoiding technology based on transform-domain design is first introduced, and the implementation scheme of interference- avoiding system based on DFT design is presented in detail. The simulation tests were run for several interference scenarios, and the results indicate that the performance of interference avoiding design system based on DFT is superior to that of one based on DWT. Moreover, The design system based on DFT provides a significant interferenceavoiding improvement over a DS-SS system and a non-interference suppressing system.
Keywords:transform- domain design  interference- avoiding  spectrum management  cognitive radio
