This study deals with the asymptotic performance of a multiple-spur cancellation scheme.
Radio frequency transceivers are now multi-standard and specific impairment can occur.
The clock harmonics, called spurs, can leak into the signal band of the reception stage, and
thus degrade the performance. The performance of a fully digital approach is presented
here. A one-spur cancellation scheme is first described, for which we exploit the a priori
knowledge of the spur frequency to create a reference of the polluting tone with the same …
