Abstract :
A novel algorithm for the reduction of several types of noise that occur typically in wireless digital speech communications is described in this paper. The algorithm aims at reducing the spectral discontinuities of the signal by analyzing the 2D spectral map and closing the gaps between the frames using heuristic rules. Some experimental evaluations are reported.
