Method to test the broadband access for a subscriber connection line |
摘要 |
<p>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.</p> |
