| Abstract: | To achieve spectrum holes detection in cognitive satellite communication, six spectrum sensing methodologies are introduced and compared. According to their characteristics, the application of each method and the analysis of advantages and disadvantages are presented. Computer simulation results show the performances of energy detection, match filtering and compressed sensing. It is pointed out that compressed sensing is suitable for satellite communication because of minimum hardware complexity. |
