Abstract
The invention concerns a method and device for processing UHF signals for an EPC communication. The method includes the steps of picking up UHF signals by an antenna of the device for processing UHF signals, creating an envelope signal from the UHF signals picked by the antenna in a demodulator, processing the envelope signal and decoding critical TRcal symbol and data in a logic unit of the device. Furthermore, the method includes the steps of interpreting the critical TRcal symbol and data, storing the interpreted data, encoding transmit data, modulating by encoded data in a modulator, and clocking the steps as above by a local oscillator. In the step of processing the envelope signal, the critical TRcal symbol is processed by a high frequency clock and data are processed by a low frequency clock.
