20.500.12556/RUL-136193 Phase detection and modulation improvement for active load modulation during continuous transmission The paper covers one of the communication technologies used in wireless sensor networks. We have presented improvements in existing radio frequency identification (RFID) systems to address the problem of the phase selection in active load modulation (ALM). The phase selection affects the interoperability of communication devices and has to be addressed in the design phase of a new tag. A novel transmission method is presented to make the phase selection irrelevant for device interoperability. A second solution is shown to improve the existing system synchronization, which allows operation with arbitrary selected phase. A mathematical analysis of signals present on the antenna was used together with the reference reader model to perform an analysis of proposed improvements. We proved that the proposed transmission method is less affected by phase selection. Furthermore, we demonstrated that existing system improvement allows synchronization and operation at an arbitrarily selected phase despite the continuous transmission and large signal-to-interference ratio. wireless sensor networks radio frequency identification near field communication active load modulation binary phase shift keying interference measurement brezkontaktne senzorske mreže radiofrekvenčna identifikacija RFID komunikacija v bližnjem polju NFC aktivna bremenska modulacija BPSK modulacija interferenčna meritev true false true Angleški jezik Slovenski jezik Članek v reviji 2022-04-19 09:42:46 2022-04-19 09:42:46 2022-09-15 04:13:31 0000-00-00 00:00:00 2021 0 0 16 str. iss. 18, art. 6155 Vol. 21 Sep. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 681.5 1424-8220 10.3390/s21186155 79864067 sensors-21-06155.pdf sensors-21-06155.pdf 1 5358C8B39B84E5CF6E76EE5CA46E86C2 1009a1edae3e170be6845b90661a4931887188d10c4cc62fbc714542d1e9225a 8a4854c6-bfb4-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155708 https://www.mdpi.com/1424-8220/21/18/6155 1 3ded8f16-bfb4-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155707 Fakulteta za elektrotehniko 0 0 0
