Software Defined Radio for RFID Application
Radio Frequency Identification (RFID) is currently the
hottest technology in wireless applications area. Its unique advantages such as
data transmission with extreme low power or even without power in tag can be
the biggest beneficial for goods management.
Software-Defined Radio (SDR) is a
wireless communications system where all of the signal processing is
implemented in software. By simply downloading a new program, a software radio
is able to interoperate with different wireless protocols, incorporate new
services, and upgrade to new standards.
In this paper, we build an RFID
application simulation environment over the SDR. We do the source to sink
transmission simulation by using Quadrature Amplitude Modulation, Then, we
compare the differences of BER versus SNR performances for input and output
signals.
Whether we realize it or not, radio frequency identification
(RFID) is an integral part of our life. RFID increases productivity and
convenience. RFID is used for hundreds, if not thousands, of applications such
as preventing theft of automobiles and merchandise; collecting tolls without
stopping; managing traffic; gaining entrance to buildings; automating parking;
controlling access of vehicles to gated communities, corporate campuses and
airports; dispensing goods; providing ski lift access; tracking library books;
buying hamburgers; and the growing opportunity to track a wealth of assets in
supply chain management. RFID technology is also being pressed into service for
use in U.S. Homeland Security with applications such as securing border
crossings and intermodal container shipments while expediting low-risk
activities.
