Abstract
A method of sharing spectrum with a legacy communication system includes acquiring spectrum correlation of the legacy communication system, and generating a transmit waveform based on the spectrum correlation. Unlike conventional cognitive radios that utilize spectrum holes only, the proposed method can also utilize spectrally correlated frequency components where primary-user signals are present.
