Penyiasat RFID konvensional menggunakan pengesan berasaskan simbol-demi-simbol seperti penapis yang dipadankan dan pengesan tepi untuk pengesanan isyarat yang tidak cukup mengeksploitasi struktur bentuk gelombang yang dikodkan data. Dalam makalah ini kami mencadangkan algoritma berasaskan Viterbi untuk mengesan jujukan data sistem RFID menggunakan standard EPC-Global Generation-2. Dengan menguraikan bentuk gelombang berkod data yang berkaitan pada asas separuh kitaran, pendekatan yang dicadangkan mula-mula memindahkan perwakilan skema pengekodan data kepada gambar rajah trellis dan dengan itu membawa kepada penggunaan algoritma Viterbi untuk anggaran jujukan data. Selain itu, berbeza daripada algoritma Viterbi tradisional yang menggunakan pekali korelasi sebagai metrik cawangan, algoritma yang dicadangkan menggunakan pekali korelasi mutlak sebagai metrik cawangan kami yang betul-betul boleh menjimatkan kerumitan pengiraan algoritma Viterbi sehingga 50 peratus. Berbanding dengan pendekatan konvensional, algoritma yang dicadangkan boleh meningkatkan prestasi sistem dengan ketara disebabkan oleh eksploitasi penuh struktur isyarat jalur asas.

Abstract: Conventional RFID interrogators use symbol-by-symbol-based detectors such as the matched filter and the edge detector for signal detection which do not sufficiently exploit the structure of the data-encoded waveforms. In this paper we propose a Viterbi-based algorithm to detect the data sequence of the RFID systems using the EPC-Global Generation-2 standard. By decomposing the associated data-encoded waveform on a half-cycle basis, the proposed approach first transfer the representation of the data-encoding scheme to a trellis diagram and thus leads to the application of the Viterbi algorithm for data sequence estimation. Also, different from the traditional Viterbi algorithm using correlation coefficient as the branch metrics, the proposed algorithm uses the absolute correlation coefficient as our branch metric which can exactly save the computational complexity of the Viterbi algorithm up to 50 percent. As compared to conventional approaches, the proposed algorithm can significantly improve the system performance due to its full exploitation of the baseband signal structure.
