  • 简介:Arobustdigitalreceiverbasedonamatchedfilter(MF)isproposedfortheradiofrequencyidentification(RFID)readersystemtoenhancethereliabilityofsignalprocessingintheelectronicproductcode(EPC)sensornetwork(ESN).Theperformanceoftheproposedreceiverisinvestigatedbyexaminingtheanti-collisionalgorithmintheEPCglobalClasslGeneration2protocol.Thevalidityandusefulnessaredemonstratedbybothcomputersimulationsandexperiments.Basedontheverificationresults,comparingwiththeconventionalzerocrossingdetector(ZCD)basedreceiver,theproposedreceiverisveryrobustagainststrongamplitudedistortionsandconsiderablefrequencydeviationshappeningonthebackscatteredsignalfromapassivetag.
