摘要：

A　fast　algorithm　for　frequency　delay　of　arrival　(FDOA)　estimation　based　on　fourth-order　cumulant　is　studied.　The　traditional　method　has　a　large　amount　of　calculation　and　the　parameter　is　estimated　slowly.　This　paper　proposed　a　fast　algorithm　to　improve　the　traditional　methods　by　using　sliced　fourth-order　cumulant　and　applying　minimum　norm　solution　to　solve　the　matrix　equation　optimally.　Experiment　shows　that　fast　algorithm　can　accurately　estimate　the　FDOA,　and　some　parameters　such　as　sample　points　and　SNR　have　an　impact　on　the　estimation　accuracy.　©,　2015,　Beijing　University　of　Technology.　All　right　reserved.
