TRANSPONDER, READER, METHOD OF OPERATING A TRANSPONDER, AND METHOD OF OPERATING A READER

摘要

In a method of operating a transponder (1, 51) a parallel digital data stream comprised of a plurality of digital data sequences (23-25) is generated by the transponder (1, 51). Then, a plurality of modulated signals (42-44) by modulating each of the digital data sequences (23-25) with a dedicated carrier/subcarrier of a plurality of carriers/subcarriers (26-28) is generated. The modulated signals (42-44) are orthogonal to each other.
