“…In the downlink communication, the PIE (Pulse Interval Code) is used in the encoding course according to EPC protocol. As shown in Fig.1, Tari of PIE is the reference interval based on EPC protocol type A [2]. As one pulse of the above code can represent a number of binary symbols, it is more appropriate in high-speed transmission system [3].…”

This paper proposed a RFID base-band transmission model based on the analysis of RFID base-band communication course, in which FPGA technology is employed to design a communication IP core, integrating functions of base-band encoding & decoding and data transmitting. The RTL design of base-band communication IP core based on modular method is also presented. The experimental studies based on Quartus Ⅱ and Simulink simulating tools indicate that the proposed communication model is fully feasible, providing a highly-integrated baseband communication IP core.

“…In recent years, reader-talk-first (RTF) RFID tag identification protocols have seriously been investigated as new improvements in silicon technology and digital signal processing technology have mitigated or overcome the major shortcomings of RTF protocols: complex circuitry and reader interfe-rence problem, and the capability of RTF protocols on detecting large populations of tags in a short time period has been observed. RTF tag identification protocols are broadly classified into aloha-based schemes [3][4][5][6][7][8][9][10][11][12] and tree-based schemes [2,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. In aloha-based schemes [30,31], a reader predicts the number of current tags within its interrogation area and assigns estimated number of timeslots to all of the tags.…”

In large-scale RFID systems, all of the communications between readers and tags are via a shared wireless channel. When a reader intends to collect all IDs from numerous existing tags, a tag identification process is invoked by the reader to collect the tags' IDs. This phenomenon results in tag-to-reader signal collisions which may suppress the system performance greatly. To solve this problem, we design an efficient tag identification protocol in which a significant gain is obtained in terms of both identification delay and communication overhead. A k-ary tree-based abstract is adopted in our proposed tag identification protocol as underlying architecture for collision resolution. Instead of just recognizing whether tag collision happens at each interrogation time period, the reader can further obtain the reason of why the collision occurs in the current tag inquiry operation. With this valuable information, we can reduce tag signal collisions significantly and at the same time avoid all of the tag idle scenarios during a tag identification session. The rigorous performance analysis and evaluation show that our proposed tag identification protocol outperforms existing tree-based schemes.
