ABSTRACT:
A communication band is divided into a plurality of allocation channels (202, 204, 206, 208). At least one allocation channel (204) is transferred to a transform domain. The behavior of the at least one allocation channel is monitored in the transform domain in order to derive a set of statistics. The set of statistics are used to determine a channel category for the at least one allocation channel.
