A highly collision-resistive RFID system multiplexes communications between thousands of transponders and a single reader using TH-CDMA based anti-collision scheme. This paper focuses on the back-end design consideration of such an RFID system with the deployment of high-level modeling techniques, accompanying a technical comparison of physical-level description, hardware-based emulation, and software-based simulation. A new rapid-prototyping simulation system was constructed to evaluate the robustness of a multiplexed RFID link system with more than 1,000 channels in the presence of field disturbances, and the design parameters of the back-end digital signal processing that dominated anti-collision performance were explored. Finally, the derived optimum parameters were applied to the design of a back-end digital integrated circuit to be installed in collision-resistive transponder circuitry.
