Xiaomei Zhu · Jisuanji gongcheng · 2011
This paper researches the primary user's detection based on cyclostationary characteristic in non-Gaussian noise.Combining with multiple cyclostationary characteristic of primary user,through summation criteria and maximum criterion,spectral correlation functions of multiple cyclic frequencies are integrated to improve the reliability of detection results.On the basis of equal weighted sum criteria,according to different levels of cyclostationary characteristic on different cyclic frequencies,a weighted summation criterion based on spectral correlation function is proposed.Simulation results show that the cooperation of multiple cyclic frequencies can improve detection results;the weighted summation criterion has better detection performance than equal weighted summation criteria.
