ABSTRACT:
An adaptive control system for controlling the effects of narrow to medium bandwidth interferers in a wireless communications system (e.g., wireless LAN devices) by identifying which sub-carriers in a multi-carrier system are located on frequencies that are subject to interfering signals, and using only those sub-carriers that are not subject to interference for communications between wireless communications devices.
