1. A wireless communication system comprising:
- first and second wireless communications devices configured to communicate with one another via a wireless communications link having at least one settable link characteristic;
said first and second wireless communications devices comprising respective first and second orthogonal frequency-division multiplexing (OFDM) wireless transceivers and respective first and second controllers coupled thereto and configured to store short term and long term historical characteristics of interference;
said first controller configured todetect received interference,determine a type of the received interference from among a plurality of interference types comprising wideband interference, self interference, and narrowband interference based upon comparing at least one characteristic of a current received signal with the short term and long term historical characteristics of interference, andset the at least one settable link characteristic to compensate for the received interference based upon the interference type.

Abstract
A wireless communication system may include first and second wireless communications devices communicating with one another via a wireless communications link having a settable link characteristic. The first and second wireless communications devices may include respective first and second wireless transceivers and respective first and second controllers coupled thereto. The first controller may be for detecting received interference, for determining a type of the interference from among interference types comprising wideband interference and narrowband interference, and for setting the settable link characteristic to compensate for the interference based upon the interference type.

9. A wireless communications device operable to communicate with an other wireless communications device via a wireless communications link having at least one settable link characteristic, the wireless communications device comprising:
-
an orthogonal frequency-division multiplexing (OFDM) wireless transceiver; and a controller coupled to said wireless transceiver and configured to store short term and long term historical characteristics of interference; said controller configured to detect received interference, determine a type of the received interference from among a plurality of interference types comprising wideband interference, self interference, and narrowband interference based upon comparing at least one characteristic of a current received signal with the short term and long term historical characteristics of interference, and set the at least one settable link characteristic to compensate for the received interference based upon the interference type. - View Dependent Claims (10, 11)

12. A method for compensating interference in a wireless communication system comprising first and second orthogonal frequency-division multiplexing (OFDM) wireless communications devices communicating with one another via a wireless communications link having at least one settable link characteristic, the method comprising:
-
detecting received interference; storing short term and long term historical characteristics of interference; determining a type of the received interference from among a plurality of interference types comprising wideband interference, self interference, and narrowband interference based upon comparing at least one characteristic of a current received signal with the short term and long term historical characteristics of interference; and setting the at least one settable link characteristic to compensate for the received interference based upon the interference type. - View Dependent Claims (13, 14)
