| Abstract: |
We consider the problem of interpolating a continuous-time signalfrom a set of uniformly spaced discrete-time samples. One of theprime methods of interpolation is based on the use of uniformB-splines. In this paper, we introduce a new interpolationapproach using nonuniform B-splines as interpolation kernels. Weshow both theoretically, and through simulation results, thatusing nonuniform B-splines can result in a higher quality ofinterpolation with respect to uniform B-splines, at the samecomputational cost. |
