Abstract
An RFID transponder includes a coding and modulation unit that generates a transmission signal by modulating an oscillator signal with an encoded bit signal. During a first and a second time segment, the encoded bit signal assumes a first and a second logic level, respectively. The transmission signal includes a first signal pulse having a first phase within the first time segment and a second signal pulse having a second phase that is shifted with respect to the first phase by a predefined phase difference within the second time segment. The transmission signal is paused for a pause period between the first and the second signal pulse. The pause period is shorter than a mean value of a period of the first time segment and a period of the second time segment.
