Abstract
A wireless communication device is provided that is capable of suppressing out-of-channel emissions. The wireless communication device includes an upsampled broadband multicarrier signal generator and multiple upsampled sidelobe signal generators. The upsampled broadband multicarrier signal generator receives a symbol stream and, based on the symbol stream, generates a broadband multicarrier signal comprising an in-channel signal and a first multiple out-of-channel sidelobes. Each upsampled sidelobe signal generator of the multiple upsampled sidelobe signal generators receives at least a portion of the symbol stream and, based on at least a portion of the symbol stream, generates an out-of-channel sidelobes to produce a second multiple out-of-channel sidelobes. The wireless communication device further includes a combiner that combines the broadband multicarrier signal and the second multiple out-of-channel sidelobes to at least partially suppress first multiple out-of-channel sidelobes of the broadband multicarrier signal.
