Active backscatter systems - transponder, a communication system with such a and method for transmission of data with such an active backscatter systems - transponder

摘要

The present invention relates to a device - in particular an active backscatter systems - transponder - for generating an oscillator signal (s), based on a base signal (sh), with an oscillator (shfo) for the active design of the oscillator signal (s) by oscillations, an input (ant φ s φ) for the base signal (sh) and an output (ant φ s φ) for the generated oscillator signal (s), wherein the oscillator (shfo) by means of the base signal (sh) for generating of the oscillator signal (s) to the base signal (sh) which can be excited quasi-phase coherently is excitable. Dollars a to the transmission of data has such a device further comprises a data insertion of a direction (tgen), which for the insertion of data or a data signal (dat φ tx φ) in the oscillator signal (s) is designed. Dollars a, a correspondingly suitable receiver (e) for receiving and processing of a received signal (e), as a quasi phases of the coherent signal (s) of such a device was generated and transmitted, preferably has in addition to a separating means (mix) for the removal of the signal components of the oscillator (shfo) from the received signal (e) by means of the base signal inasmuch of a receiver oscillator (ehfo) also a data - recovery device (demod) for the recovery of the inserted data (dat φ tx φ) to.
