Abstract
Method and sensor system for measuring the transmission properties of a first transmission path based on feedback compensation between a first transmitter and a receiver, a compensation signal of a compensation transmitter being received in a superimposed manner in the receiver in addition to the emitted transmission signal of the first transmitter. A supply signal for the first transmitter and a receiver output signal each form a vector in a pre-Hilbert space. A Hilbert projection is performed between the receiver output signal and the supply signal so that a projection image signal is generated. An output signal is formed from the projection image signal. A pre-signal is generated by an inverse transformation of the output signal with the supply signal. A compensation signal for supplying the compensation transmitter is generated from the pre-signal formed in order to achieve feedback control of the receiver output signal.
