design of an RFID system reconfigurable on FPGA

I see at least two possible motivations to implement a RFID reader on a FPGA.

- to implement specific features that are not available with commercial RFID reader chips. This is often the case for test systems, that need to vary protocol parameters arbitrarily or measure signals that aren't usually accessible.

Multistandard capability can be a possible motivation, but you shouldn't underrate how versatile commercial reader chips are.

- to implement the functionality of existing RFID readers on a FPGA for educational purposes. You shouldn't mind to reinvent the wheel in this case.

A suitable RF frontend has to be added. Besides digital FPGA design basics, profound knowledge of DSP methods will be required for the project.
