Abstract :
In this paper a new architecture for the implementation of high performance interpolators for digital modems is presented. The architecture is based on a trigonometric interpolation algorithm. It uses a state of the art rotator architecture to improve the speed and power dissipation of the circuit. Experimental measurements of the interpolatorpsilas performance are reported.
