ABSTRACT:
An identification system in which a trigger signal, emitted on an object side and received by a portable code generator, is provided. The trigger signal is used on the object side to phase code a reference signal. The code generator encodes a response signal using the trigger signal in a phase-coded manner and retransmits the response signal. The received response signal is compared with the generated reference signal in an object-side evaluation unit using an autocorrelation function. If the value of the autocorrelation function is larger than a threshold value, an enabling signal is generated.
