SUBSCRIBER LOOP DISTURBER RECOGNITION

摘要

To identify interference from other data carrying subscriber loops (i.e., fr om loop disturbers), a power spectral density sample may be obtained from the subscriber loop under consideration based on at least one measurement while the loop is not transmitting data. The sample power spectral density may then be correlated with each one of a set of known power spectral densities. Each known power spectral density represents a pow er spectral density in a loop which is not transmitting data in the presence of one of ( i) no subscriber loop disturbers, (ii) a particular subscriber loop disturber, and (iii) particular subscriber loop disturbers. Based on the correlations, subscriber loop disturbers may be recognised.
