METHOD FOR TESTING SUBSCRIBER CONNECTION LINES FOR BROADBAND SERVICES
The method involves applying a time-discrete multi-carrier transmission signal to a test point of the subscriber connection line, measuring an echo pulse response at a test point, determining complex value random coefficients from the pulse response, forming the empirical estimate of the cross-corre...

| Zusammenfassung: | The method involves applying a time-discrete multi-carrier transmission signal to a test point of the subscriber connection line, measuring an echo pulse response at a test point, determining complex value random coefficients from the pulse response, forming the empirical estimate of the cross-correlation function of signals formed by two-dimensional discrete Fourier transformation. |
