Ron Rotstein, Randy L Ekl: Method for dynamic frequency selection. Motorola, Terri S Hughes, Indira Saladi, July 5, 2005: US06914876 (10 worldwide citation)

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. T ...
