摘要：

The　acquisition　method　of　radial　pulse　wave　is　easily　influenced　by　human　body＇s　activities.　The　transfer　function　method　was　applied　to　estimate　radial　pulse　wave　using　finger　pulse　wave.　After　the　window　size　and　the　order　of　the　model　were　being　analyzed,　the　transfer　function　FIR　model　between　radial　pulse　wave　and　finger　pulse　wave　was　set　up　firstly.　Then　the　test　data　were　used　to　estimate　the　radial　artery　pulse　wave　and　verify　the　accuracy　of　the　proposed　model.　By　analyzing　ten　subjects＇　data　acquired　in　ten　days,　the　best　waveform　match　between　the　estimated　and　the　measured　radial　artery　pulse　waves　were　in　the　range　from　70%　to　92%.　It　is　notable　that　using　the　transfer　function　method　could　estimate　radial　pulse　wave　from　finger　pulse　wave.　This　method　provided　a　new　easy　way　for　monitoring　radial　pulse　wave.　©,　2014,　Dongbei　Daxue　Xuebao/Journal　of　Northeastern　University.　All　right　reserved.
