Car door lock bidirectional data transmission and transponder distance measurement procedure exchanges short pulses with synchronization and correlation to give transmission delay

A car door lock bidirectional data transmission and transponder distance measurement procedure exchanges short microwave pulse packets in forward and return channels (I, II) with small frequency offset that are synchronized (203) in the second transponder (20) and correlated (105) in the first (10)...
