METHOD AND APPARATUS FOR SIMULTANEOUS SPECTRUM SENSING OF A PLURALITY OF WIRELESS CHANNELS USING CYCLOSTATIONARITY FEATURE DETECTION

摘要

A method and apparatus for determining the occupation of a plurality of radio - frequency channels, the method comprising: collecting baseband data streams from a plurality of L radio - frequency channels; performing upsampling on each data stream to modify a cyclo - stationarity parameter of each data stream; combining the upsampled data streams to generate a combined datastream; and performing cyclostationarity detection on the combined datastream to determine the occupation of the plurality of radio frequency channels.
