Abstract :
The performance of nonlinear interpolation filters is analysed in the presence of narrowband interference. An analytical expression for the signal-to-noise ratio improvement factor is derived and performance comparison with nonlinear prediction filters is achieved. Results show that nonlinear interpolation filters outperform nonlinear prediction filters
