Document Type and Number:
Japanese Patent JP2002521867
Kind Code:
A
Abstract:
A data carrier receives at least two carrier signals which are modulated in respect of the same signal parameter but with different modulation intensities. The data carrier has at least two demodulation stages, each of which having a sensitivity adapted to a modulation intensity used for a modulated carrier signal. The data carrier further has priority means capable of granting priority each time to one demodulation stage in such a manner that a demodulated carrier signal reaches signal processing means only from that modulation stage.
