Abstract :
In this paper, a novel realisation of an interpolator is presented. We address problems associated with the proposed interpolation in a fully digital demodulator. It´s performance is then compared to that of Farrow composition in terms of mean square error (MSE) and computational complexity. We show that the proposed method needs fewer operations per output sample and is more accurate
