Method for identifying signals from the same source

摘要

The method involves introducing a low pass filtered outgoing signal (X) to an input of a digital filter (W), and forming a differential signal (D) from a filter output signal (WX) of the digital filter and a low pass filtered arriving signal (Y). The differential signal is used to a transfer function of the digital filter so that the differential signal accepts a minimum value. An attenuation value is calculated from a performance value of the differential signal and the signal (Y). A coefficient is calculated from the attenuation value and the performance value of the signal (Y). An independent claim is also included for a device for executing a method for identifying a signal.
