WSEAS Transactions on Signal Processing publishes original research papers relating to the studying of analog and digitized signals. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with filter design and structures, signal reconstruction, speech analysis, image coding and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
