Non-service-intrusive methods for performance estimation of multi-channel communication systems

摘要

A method for estimating at least one performance parameter of a communication system with a plurality of channels between an access node and a plurality of end user nodes, said communication system being equipped with an internal crosstalk cancellation mechanism for reducing or cancelling internal crosstalk between said plurality of channels, the method comprising: collecting estimates, preferably at said access point, for at least one operational parameter of said communication system during normal operation of the communication system; and computing said at least one performance parameter based on the collected estimates for the at least one operational parameter.
