Claim Text:
1. A system for reducing orthogonal frequency-division multiplexing symbol interference, the system comprising: an antenna adapted to receive and transmit signals on a plurality of radio wavelengths; a cognitive radio engine to receive one or more signals from the antenna and to identify a licensed user location and bandwidth information from the signals received from the antenna; a modulator to receive encoded data from a cognitive radio user and to modulate the encoded data to generate modulated encoded data; an orthogonal frequency-division multiplexing transformer in electrical communication with the modulator, the orthogonal frequency-division multiplexing transformer to receive the modulated encoded data from the modulator and to transform the modulated encoded data to time domain orthogonal frequency-division multiplexing symbols; an interference suppression module comprising:
