Arrangement for characterizing transmission channel treats channel as transmission channel in channel class corresponding most closely to channel parameter extracted from signal on channel

摘要

The arrangement has a device (10) for extracting a channel parameter demonstrated on the transmission channel from a signal (12) on the channel, a device (14) for comparing the extracted parameter with a number of predefined channel parameters, each associated with a channel class from a number of classes and a device (16) for treating the channel as a transmission channel in the class corresponding most closely to the extracted channel parameter. AN Independent claim is also included for the following: a device for correcting distortion in a transmission channel, a method of characterizing a transmission channel, a method of correcting distortion in a transmission channel and a transmitter.
